摘要:

The first European Winter Conference on Plasma Spectrochemistry was held in Leysin, Switzerland in 1985, and the conference has taken place every odd-numbered year since then. The 13th conference in the series will be held in Graz from February 15–20, 2009. Graz is a beautiful old city (its historic town centre is a UNESCO World Cultural Heritage site) located in the south-east corner of Austria. The conference venue, Grazer Congress, has excellent facilities and is perfectly situated right in the middle of the old town.The 2009 conference will encompass the major topics covered in recent meetings, such as: fundamental plasma processes and the latest advances in instrumentation; laser-assisted plasma spectrochemistry; stable isotope measurements; quality control through certified reference materials; and elemental speciation. In addition, applications using plasma source techniques, particularly ICPMS, will be a focus of the meeting. ICPMS, a technique that was in its infancy at the first winter plasma conference in 1985, has developed rapidly and is now a mature analytical method with applications in many and diverse research areas. Thus, ICPMS is increasingly used as a sensitive quantitative tool in scientific research and industry in areas such as clinical analysis, biological and environmental studies, geological research, forensics, and mining and exploration. We can expect a good representation of papers on modern applications in these areas at the Graz conference.The format of the meeting is designed to encourage discussion between participants—pure plasma spectrochemists, analytical chemists, and other scientists using plasma spectrochemistry methods. We hope to create a relaxed environment conducive for such exchange by having short focussed talks with ample time for discussion between presentations. There will also be plenty of discussion time between sessions with comfortable breaks for coffee, a lunch break long enough to enjoy some local food (and perhaps a wine) with colleagues, and a poster session primed for easy exchange of information.The Winter Plasma Conference 2009 will also have a fresh look in terms of invited lectures. All invited lectures will be plenary,i.e.delivered to all conference participants, whereas other lectures will be held in two parallel sessions. The plenary speakers have been asked not to give the “traditional” overview lecture, but rather to present their very latest results, to tell us what is exciting and important in their field, and to connect their research topic with the other conference themes. This is a daunting task, and for this reason the scientific committee has chosen active dynamic researchers, from well-respected research groups, able to impart their knowledge with clarity and enthusiasm.The social program for the 2009 conference is also receiving considerable attention by the organising team. A hot plasma party on Monday night at the local brewery will be balanced by the conference dinner on Wednesday evening held in the beautifully restored banquet hall of the old university building in the centre of the Graz. Tours of the historic old town of Graz will be available throughout the conference, and visits to nearby ski fields and thermal bath areas are also planned.It is customary forJAASto publish a special issue containing key papers from the conference, and this will again be the case for the 2009 conference. On this occasion, however,JAASwill be the sole journal covering the conference, and the aim is to publish the special issue within six months of the conference thereby enhancing the relevance and impact of both the presented work and the subsequent published papers. To facilitate this process, a tight submission deadline will need to be set. Ideally, potential contributors to the special issue would have a good draft manuscript ready at the time of the conference, which could then be improved based on discussions at the conference.The European Winter Conference has been for many years the major forum for discussing the latest in the fundamentals and applications of plasma spectrochemistry. We welcome you to Graz next February to help continue this tradition.

摘要:

During November 19th–21st “the first and last” “International Symposium on GDOES for Surface Analysis” took place in Keio University, Yokohama, Japan. It was organised by Professor Kenichi Shimizu, a famous scientist well known for his electrochemical production of thin and ultra-thin layers and their characterisation by various analytical tools. Professor Shimizu felt that there was a lack of awareness and on the application of glow discharges for the analysis of thin layers, in a research area where glow discharges have to compete with well established methods such as Rutherford backscattering (RBS), secondary ion mass spectrometry (SIMS), proton induced X-ray emission (PIXE), Auger spectroscopy (AES), electron spectroscopy for chemical analysis (ESCA) and total reflection X-ray fluorescence (TXRF). Therefore Professor Shimizu invited around fifteen scientists from all over the world, all well known experts from different analytical methods or application areas, to present an invited lecture and to stimulate and participate in discussions on novel applications of conducting as well as of non-conducting materials. The latter materials are believed to pose a significant challenge for analytical instrumentation even today. In addition to the invited lectures, a poster session was organised covering different aspects of the technique. As a result, poster prizes were awarded to the best five presenters. The whole conference took place at Keio University, in a very friendly atmosphere, which was a prerequisite for all fruitful discussions. The surroundings of the conference site were dominated by the majestic shadow of the Mount Fuji on the horizon, making every problem seem even smaller.After a warm welcome from Professor Ichiro Inazaki, the Dean of the faculty, and Dr. Masao Horima, Honorary President of the Symposium, Siegfried Hofmann from the MPI of Metal Research based in Stuttgart, Germany, gave an excellent summary of the definitions as well as the analytical figures of merit of surface analytical methods, and this was a good point of reference for the whole conference as it gave all participants the same language for discussions and inter-comparisons. Additionally, he described the state of the art of Auger spectroscopy and highlighted the needs for future applications.L–R: P. Chapon (Jobin Yvon Horiba, France), Miss Le Costumer, P. Le Costumer (Bordeaux University, France), G. E. Thompson (UMIST, UK), N. Jakubowski (ISAS, Germany), R. K. Marcus (Clemson University, USA), V. Hoffmann (IFW, Germany), R. Payling (University of Newcastle, Australia).M.G. Dowsett, Department of Physics, University of Warwick, UK, demonstrated (using selected applications) the advantages of ultra-low energy SIMS to overcome beam-induced atomic mixing in the upper layers, thus improving the depth resolution significantly.Richard Payling from the University of Newcastle, Australia, a well known as a consultant for Jobin Yvon Horiba company, gave an overview about recent advances in theory and techniques in rf-GDOES and presented his latest specialism, the calculation of emission lines and line intensities in GDOES, available in recent book as well as on CD-ROM.Renate Gijbels (co-author Annemie Bogaerts; see their article inJAAS1), University of Antwerp, Belgium, discussed recent results of theoretical calculations of technical and analytical glow discharges, among which are rf-discharges as well as those in which flowing gases dominate the transport of ions by diffusion to the walls. Densities of different species, their velocities, temperatures, emission yields and many more of the various forms of glow discharges were presented, giving the audience a good understanding of the dominant physical processes taking place.Phillipe Belenguer, Centre de Physiques des Plasmas et de leurs Applications, Toulouse, France, presented a new approach for calculation of the physical and electrical rf discharge parameters, for instance the cathode sheath thickness, the impedance of the source and the plasma as well as the voltage current characteristics as a function of time, so that in future rf generators as well as matching units can be more easily developed to be fit for purpose.Kazuaki Wagatsuma, IMR, Tohoku University Japan, demonstrated in various applications the capabilities of modulated discharge voltages in dc and rf-sources and their phase-locked amplification in optical emission spectroscopy. Using this approach he had successfully improved the signal to noise ratio measured by more than one order of magnitude.Philippe Le Costumer, Department of Applied Geosciences, Bordeaux University, France, used various analytical tools, including GDOES, to characterise analytically the properties of glasses, especially at the surface or the interface or inter-phases between coated surface layers and the bulk material. Although low powers of rf-GDOES were used, thermal effects could not be neglected, so that for such application the techniques still needs to be improved, for instance by power modulation.Volker Hoffmann, Leibniz Institute for Solid States and Material Research, Dresden, Germany, showed that the reflectivity of a sample surface can increase the emission intensity of the line measured, causing problems for calibration (see his article inJAAS2). Additionally he showed an example of how in multi-layers consisting of non-conducting/conducting interfaces selective sputtering can complicate interpretation of the element distribution in layers by charging of non-conducting islands on a metallic substrate, thus de-focusing the bombarding ions from the glow.Kenichi Shimizu, Keio Univerity, Yokohama, Japan, the organiser of this meeting, presented his recent results of anodic oxidised Al and Ta. In his lecture he highlighted the point that with rf-GDOES he has a tool which is less expensive than more sophisticated surface analytical techniques but can give valuable information even at a layer thickness of less than 10 nm.Nerea Bordel described some of the work recently being conducted in Alfredo Sanz Medel’s group at Oviedo University in Spain. They had investigated a commercial rf-GD-AES as well as a home-built DC-GD-TOF-MS and therefore could give a comparison of both techniques. In particular, their modular approach to a new glow discharge (see their article inJAAS3) looks convincing in terms of the application of technical layers shown.Ken Marcus, Clemson Univerity, Clemson, USA, focussed his presentation on answering the question as to where we are coming from in glow discharge spectroscopy and where we might be going in the future. He convinced the audience that even scientists can learn from history in order to develop the instrumentation needed for the future.Norbert Jakubowski, Institute for Spectrochemistry and Applied Spectroscopy (ISAS), Dortmund, Germany, described his groups’ experience in home-built instrumentation in glow discharge mass spectrometry. He presented an approach using absolute sensitivity factors (useful yields) to convert the intensity/time profiles measured in the analysis of thin Ni/Cr layers to concentration/depth profiles wanted. He presented the first results of an rf-driven Grimm-type ion source operated at high powers (80 W) with high gas flow rates up to 300 ml min−1, which they had coupled to an ICP-SFMS (Axiom, ThermoElemental, Winsford, UK). They have achieved 2 orders of magnitude improvement in comparison to their low flow rate GD source coupled to a quadrupole mass analyser.L–R: Professor G. E. Thompson, two Geishas, Dr. Horiba, Professor Kenichi Shimizu.Michael R. Winchester, National Institute of Standards and Technology, Gaithersburg, USA, gave a comprehensive overview of the standards and standard reference materials for GDOES. The outcome of his lecture was that although a couple of standards and certified standard reference materials with conducting layers are commercially available for GDMS there is still a lack of reference materials for non-conducting single and mutli-layer samples of advanced materials.Kim Marshall, Leco Corperation, St. Joseph, USA, discussed the advances of GDOES in comparison to well established techniques for surface analysis (Auger spectroscopy, ESCA, SIMS). He showed the market niches and special applications where GDOES can compete well or even is superior in comparison with the above-mentioned techniques.Finally, Patrick Chapon, Jobin Yvon Horiba, Paris, France, presented a broad overview of novel applications from industry. Most impressive was the new sample holder for automatic sample changing and cleaning of the source. He pointed out that even for bulk analysis GDOES can be used, giving a reproducibility of better than 3%.

摘要:

5th International Symposium on Speciation of Elements in Biological, Environmental and Toxicological Sciences, Almuñécar, Spain, September 13–16, 2003The 5th International Symposium on Speciation of Elements in Biological, Environmental and Toxicological Sciences took place in September 2003 in Almuñécar, Spain. In continuance of the scientific tradition of this symposium it provided a forum for extensive discussion of recent progress in analytical methodology for element speciation. The conference Chairman, Ignacio Garcia Alonso, and his organizing committee from University of Oviedo did an excellent job: setting new standards in conference organization was the motto of the Spanish team and indeed more than 130 participants spent a marvellous time in a hotel located along the beach of San Cristobal. Approximately 50 invited and contributed oral presentations covered an area that ranged from the determination of inorganic compounds and complexes, oxidation states and isotopic compositions to organic and organometallic complexes and, finally, the investigation of macromolecular compounds.Already from the first day of the conference it became clear that speciation analysis is now evolving its face and its scope. No longer is this subject restricted to the determination of a metallic element in its different redox states or to the determination of low molecular mass organometallic compounds, as was the case in the early pioneering work in this field.Joseph Caruso(University of Cincinnati), the first invited speaker, declared proteomics to be a heavy focal area of future speciation research. With the focus shifting from the well defined, mostly anthropogenic, low molecular mass compounds to less defined (in most cases even unknown) biogenic high molecular mass species, the choice of detection technique has become an important issue. These mostly explanatory studies aimed at elucidating the mechanism of biotransformation of inorganic metal ions require multidimensional separation protocols and the parallel use of different mass spectrometric techniques.Maria Montes-Bayon(University of Oviedo) complemented this opening by discussing analytical strategies employing element-specific ICP-MS in parallel to molecule-specific MALDI-MS and ESI-MS for elucidation of Se uptake in the Se hyper-accumulating plantBrassica juncea.Jörg Feldmann(University of Aberdeen) reported another fundamental study on phytoremediation: arsenic hyper-accumulation inPteris vittata. Hyphenated ICP-MS and ESI-MS techniques were applied to characterize the ligands that are bio-induced upon metalloid stress.Delegates at the 5th International Symposium on Speciation of Elements in Biological, Environmental and Toxicological Sciences.Generally, the two metalloids As and Se traditionally occupy the centre of attention in speciation research. Interest in As and Se was still vivid at the conference but it was evident that speciation research is no longer limited to a few well-characterized species, as evidenced from a number of presentations devoted to these elements.Helle Rüsz Hansen(University of Aberdeen) showed the potential of HPLC-ICP-MS and HPLC-ESI-MS for the speciation of unknown As species. A new arsenosugar metabolite was determined in the urine of sheep after arsenosugar ingestion.Jens Sloth(NIFES, Norway) reported on novel As species in marine samples andErik Larsen(Danish Veterinary and Food Administration) addressed the question of the speciation and fate of supplemented Se in the human body.Bente Gammelgaard(Danish University of Pharmaceutical Sciences) tackled the challenge of seleno-sugar determination in human urine after nutritional Se supplementation. Purification and pre-concentration, necessary for molecule specific mass spectrometric detection, still resulted in co-elution of two potential metabolites. Hence, additional CE and RP-HPLC methods for the separation of these co-eluting seleno-sugars were developed.Yasumitsu Ogra(Chiba University) illustrated his research on the determination of seleno-metabolites in rat urine andJuris Meija(University of Cincinnati) explored the chemistry of aliphatic diselenides.Sandra Mounicou(University of Cincinnati) investigated the presence of selenocysteine containing proteins in plant samples. With the attention turning to arsenic,Dirk Wallschläger(Trent University) presented impressive results concerning arsenic cycling and fate of As in ground water systems.Yu-teh Chung(National Tsing-Hua University, Taiwan) was awarded a poster prize for his innovativein-vivostudy of the dynamic change of arsenic metabolites in rats using microdialysis combined with µLC-ICP-MS.Since metalloproteins and other metallobiomolecules are currently the most challenging issue in speciation, different instrumental approaches for ICP-MS detection of non-metals such as phosphorus and sulfur, important constituents of such species, were discussed extensively. The group ofAndreas Prange(GKSS Research Centre) pioneered the alternative approach of protein quantification by S measurement.Andreas PrangeandNorbert Jakubowski(ISAS Dortmund) both presented different biological applications of sulfur and phosphorus determination, ranging from metalloproteins, DNA nucleotides to phosphor containing pesticides and herbicides. The presented instrumental concepts for elimination of spectral interferences were two-fold application of high mass resolution and energy discrimination in a collision cell ICP-MS. Multi-element capability was preserved despite using the ion–molecule chemistry in a cell. Moreover, Norbert Jakubowski showed the potential of LA-ICP-MS for the analysis of metalloproteins on blot membranes.The quantification of trace elements in proteins remains an important challenge.Koen De Cremer(Ghent University) reported results of his investigations on vanadium complexes in cytosol by SEC-ICP-DRCMS. The association of various elements with proteins has been investigated byJörg Bettmer(University of Mainz), focusing on speciation in biological materials.Accurate quantification of the species using hyphenated ICP-MS techniques presents a challenge to analytical sciences. Generally, the ability to perform isotope ratio measurements and, as a consequence, isotope dilution analysis play a key role in ICP-MS. Although isotope dilution (ID) ICP-MS has been widely employed for trace element analysis in a wide variety of sample matrixes, its application to species-specific determinations has so far been limited. Isotope dilution ICP-MS provides accuracy and superior uncertainty figures over other calibration strategies.Klaus Heumann(University of Mainz) discussed the importance of species-specific isotope dilution for method validation. His presentation concluded that the number of available species-specific enriched spikes is increasing. Several presentations utilizing species specific IDMS confirmed this trend.Eva Krupp(University of Pau) showed the quantification of organotin (DBT, TBT) in sediment and methylmercury in fish by GC-ICP-MS. AlsoRosa Rodriguez Martin-Doimeadios(University of Pau) has studied mercury methylation/demethylation processes in estuarine sediments by GC-ICP-MS, using species-specific enriched stable isotopes.Pablo Rodrígueuz-González(University of Oviedo) discussed the methodology for the analysis of butyltin compounds by ID based on a sophisticated triple spike approach. This method is a useful tool for assessment of species interconversion during sample pre-treatment.Speciation is no longer a purely academic subject. Various industrial sectors, government and legislative bodies are becoming involved, as stated byRita Cornelis, one of the pioneers of elemental speciation analysis. Nevertheless,Roberto Morabito(ENEA Rome) presented the concept of EU-SM&T projects for the production of reference materials.Ralph Sturgeon(National Research Council of Canada, NRC) discussed the philosophy of reference material production at the NRC. Cooperation and experience exchange is another strategy towards applications apart from purely academic research.Michael Sperlingintroduced a new European initiative, the European Virtual Institute for Speciation Analysis (EVISA), an internet platform founded to provide the missing link between the research laboratories and the potential users from industry (seehttp://www.speciation-analysis.net/).The future research direction of the field of elemental speciation was elegantly summarised byDavid Amouroux(University of Pau). His lecture clearly showed that the key for fundamental understanding of metals and organometals in the environment was the implementation of integrated chemical and biological investigations. Excellent examples of interdisciplinary strategies allowing a detailed insight into the fate of organometallic species of mercury and tin in ecological systems were presented.The local organising committee from University of Oviedo. TopL–R: Nacho Garcia Alonso, Cristina Sariego Muñiz, Juan Marchante Gayon, Giuseppe Centineo, Gloria Alvarez Llamas, Andrés Rodriguez Cea, Laura Hinojosa Reyes, Pablo Rodriguez Gonzalez, Marisa Fernandez Sanchez and Paula Braga Riera. BottomL–R: Rafa Pardo, Vanesa Diaz Huerta, Elisa Blanco-Gonzalez and María Montes Bayon.It is self-evident that this report covers only some selected highlights on perspectives in speciation. Many more interesting presentations contributed to the success of this symposium. We spent a very delightful time in Almuñécar and by the end of the conference all participants were not only enlightened and fuelled by new challenges in speciation analysis, but had also got acclimatised to the afternoon siesta and the extremely late dinner practised by the typical Spaniard.Gunda KoellenspergerBOKU–Vienna Institute of Chemistry

摘要:

IntroductionThe development of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) as a solid sampling technique has been widely described.1–4From the early experiments with IR lasers,5the development moved quickly towards the use of shorter wavelengths and UV lasers. Shorter wavelengths improved the laser–sample interaction primarily for transparent samples, such as quartz or fluorite. Several types of lasers with different wavelengths are now in use depending on application and budget. Today's most widespread used laser ablation systems for ICP-MS or inductively coupled plasma optical emission spectrometry (ICP-OES) are based on Nd:YAG lasers operating at the fourth harmonic at 266 nm in the ultraviolet.Commercially available Nd:YAG laser ablation systems reach a maximum pulse energy of ∼6 mJ at 266 nm leaving the laser head. Some of this energy is lost in the optical beam delivery path especially if an aperture for spot shaping is used. In this case an increasing part of the energy is lost using smaller apertures to obtain small ablation craters. An alternative is the use of a beam compressor lens system, which maximizes the energy extraction through the aperture for each spot size. This leads to higher energy densities and towards smaller crater sizes on the sample, but is not suitable for obtaining a constant energy density over the most commonly used range of crater diameters (5–300 µm). The influence of the wavelength on elemental fractionation, as defined inref. 6, has been studied in detail.7–9Elemental fractionation is stillseen as one of the drawbacks of this technique,10–15even if only a limited number of elements are affected.Mank and Mason reported a significant influence of the crater depth-to-diameter ratio on elemental fractionation during the ablation process,16which as a result requires (in order to visualize this effect) a constant sample uptake rate independent of the crater diameter. In comparison to the more “flat-top” beam profiles of excimer lasers, the Gaussian beam profile of a Nd:YAG laser makes it more difficult to ensure a homogeneous illumination of the laser beam onto the sample surface. The advantage of an ArF 193 nm excimer laser ablation system, equipped with homogenizing optics, has been demonstrated inref. 17. This system allows the adjustment of the crater size between 4 and 120 µm, while maintaining constant energy densities of up to 40 J cm−2, and has been successfully applied to a number of applications.18,19A comparison of various wavelengths (157, 248, 213 and 266 nm), as reported inrefs. 7 and 8, indicated that the wavelength has less influence on elemental fractionation. In contrast, a comparison between a 266 nm Nd:YAG and a 193 nm excimer laser ablation system20indicated significantly reduced elemental fractionation using the shorter wavelength, which allows the conclusion that the optical system used has an influence on the ablation process. Due to the low acceptance of excimer lasers, partially based on price, size and the use of a fluorine-containing gas, the improvement of the ablation characteristics of the most used 266 nm Nd:YAG laser are of great interest. Jeffrieset al.21showed that a low energy quintupled Nd:YAG (213 nm) laser ablation system improved the ablation characteristics andreduced elemental fractionation, in comparison to a quadrupled Nd:YAG (266 nm) system. However, the energy density of such a 213 nm system seems to be at the low end of the optimized conditions necessary to ablate the whole range of opaque and transparent samples.This work describes the design of a high power 266 nm Nd:YAG laser ablation system equipped with homogenizing optics. The new optical system of the 266 nm Nd:YAG laser ablation system is partially adopted from that of the excimer laser system described inref. 17. Results obtained concerning beam homogeneity, ablation rate, signal stability, reproducibility and preliminary results on elemental fractionation are reported. A well-characterized reference standard MPJ-DING22was used to compare the quantitative results achievable using the new laser ablation system.

摘要:

Welcome to issue 1 ofJAAS, 2005. The first issue of the year is a good time to bring to your attention the changes which have occurred in 2004, and highlight new developments for the coming year.The major change last year was the retirement of Joseph Caruso, Cincinnati, USA, as Chair of the Editorial Board in the summer. Joe had served on the Editorial Board since 1998. He was the first North American Chair ofJAASand under his guidance the Board became more international. We are delighted that Joe will continue his involvement with the journal as a member of the Advisory Editorial Board.1Gary Hieftje, Bloomington, Indiana, USA, who joined the Editorial Board in 2001, took over the role of Chair from Joe.2Gary has been involved withJAASright from the start as a member of the Advisory Board. In fact, the very first issue of the journal contains an Atomic Spectrometry Viewpoint, in which he was interviewed by the first Editorial Board Chair, John Ottaway.3Stephen Hill, Plymouth, UK, retired at the end of 2004 after 10 years on the journal Editorial Board. Steve is Chair of the Atomic Spectrometry Updates Board4and has played a significant role in developing the ASU reviews to become more critical and cover emerging areas.2004 also brought technical innovations to improve our services toJAASauthors, referees and readers.January 2004 saw the launch of the RSC’s Journals Archive. This fully searchable archive provides access to over 200 000 articles in 1.2 million pages published from 1841 to 1996. Readers can browse articles fromJAASfrom its launch in 1986 and its forerunner,Annual Reports on Analytical Atomic Spectroscopy, from 1971. Articles fromThe Analystare available from 1876! For more details, please visitviawww.rsc.org/archive.In October 2004 we announced the launch of ReSourCe, the RSC’s service for authors and referees, which streamlines the electronic submission and review processes. Authors can submit and track their manuscripts and collect pdf reprints, whilst referees are able to download articles for review, submit their report and see the outcome of manuscripts they examined. All this is available through a single entry point. For more information visitwww.rsc.org/resourceor read our recent editorial.5New for 2005, you may already have noticed several changes to the look and feel ofJAAS. The most obvious is the new front cover, a new style and design which extends across all RSC journals. We are looking to authors to provide eye-catching artwork to feature on the cover. If you have an image you would like to be featured alongside your paper, please contact the Editorial Office.This issue also sees the introduction of illustrated contents entries to enhance the impact of papers inJAAS. You will see that we now encourage authors to supply colourful images to attract readers’ attention along with a short statement to highlight the novel aspects of the work reported. We do hope that this will make the contents ofJAASmore attractive and easier to browse.Also in this issue appearsChemical Science, which draws together the news and research highlights from all RSC publications, it provides a ‘snapshot’ of the latest developments across the chemical sciences.Chemical Sciencewill appear monthly as a free supplement in the front ofJAASas well as other RSC publications, and will also be available online, atwww.rsc.org/chemicalscience.We also see the publication of our first Perspective article: Is it still possible, necessary and beneficial to perform research in atomic emission spectrometry? This personal view of the field by Jean-Michel Mermet appears in this issue.6In 2005 we will bring you two special collections of papers. The first will arise from the forthcoming European Winter Conference, and later in the year a Guest Editor issue on Chemical Metrology, co-ordinated by Hywel Evans and Mike Sargent, will be published.Finally, next year,JAASreaches its 21st volume and the journal will be celebrating its coming-of-age. Plans for these celebrations are already underway: we hope you will join us in them and will bring you further details soon.We look forward to receiving your papers throughout the coming year. We also value and welcome your comments and suggestions forJAAS. Please do feel free to contact a member of the Editorial Board or myself in the Cambridge Editorial Office. We look forward to hearing from you.Claire DarbyManaging Editor

摘要:

The 2nd Euro-Mediterranean Symposium on Laser Induced Breakdown Spectroscopy (EMSLIBS-II), organized by IESL-FORTHThe Institute of Electronic Structure and Laser is part of the Foundation for Research and Technology-Hellas and is located in Heraklion, Crete, Greece.with support from the European Research Office of the US Army Research Laboratory, took place in the resort village of Hersonissos, Crete, Greece, from September 30th to October 3rd, 2003. For this purpose over 80 scientists, including 25 students, from 20 countries came together on the island of Crete, a symbolic location in the Mediterranean, which since ancient times has been the bridge between Europe, Asia and North Africa.This special issue ofJAASfeatures selected papers presented during EMSLIBS-II. The symposium scientific program included 11 invited lectures, 28 contributed oral and 28 poster presentations. The scope of the symposium covered most of the LIBS thematic areas, ranging from fundamental studies to analytical applications and novel instrumentation. LIBS, also known as LIPS (laser induced plasma spectroscopy) is a straightforward analytical technique, which exploits the spectrochemical information contained in a transient micro-plasma, generated upon focusing light from a pulsed laser on a sample (solid, liquid or gas) that is being analysed. Following pioneering work in the early 1980s by L. Radziemski and D. A. Cremers at the Los Alamos National Laboratory, an increasing number of scientists have been involved in LIBS research recognizing its potential in chemical analysis. Relatively simple instrumentation, speed of analysis and need for minimal or no sample preparation are among the attributes which make LIBS an attractive analytical method for probing the elemental content of materials. These features in combination with recent advances in laser sources, spectrometer and detector technologies have led to a considerable expansion of research activities worldwide in a broad array of analytical applications and novel, flexible instrumentation.To this end, special emphasis, during EMSLIBS-II, was placed on the portable (or mobile) LIBS sensors, an emerging technology that shows great potential for field applications and real time analysis of materials relevant to a variety of problems in industry, environmental monitoring or even non-civilian applications. The latest developments in portable LIBS technology were covered in two oral presentation sessions, while future prospects were highlighted during the symposium panel discussion. Research interest has focused recently on the use of double pulses in LIBS analysis. This has resulted from breakthrough observations of signal enhancement following sample irradiation with two pulses separated in time by a few microseconds. The increased interest was reflected in the two dual-pulse LIBS sessions held on the first day of the conference. The remaining oral presentations and the poster session covered applications from industry, environmental monitoring, cultural heritage, life sciences, and the use of femtosecond lasers in LIBS analysis.In addition to the scientific sessions, laser system and spectroscopic detector manufacturers (Andor Technology, Quantel, New Wave Research and Ocean Optics) participated in the exhibit session during the symposium, presenting their latest products in relation to LIBS technology.

摘要:

Dear colleagues and friends,We wish you all a happy, healthy and successful 2010, which will be a special year for all of us. TheJournal of Analytical Atomic Spectrometrycelebrates its 25th anniversary this year and we are delighted to be able say thatJAASis one of the leading journals in its field. The manuscripts published inJAASover the last 25 years cover the entire spectrum of analytical methods and techniques important for element and trace element analysis, isotope ratio determinations and of course speciation techniques, data processing, and statistics. A variety of new strategies, methods, instrumentation and sample introduction systems have been described in an impressive number of articles and many of these strategies are now applied in various research laboratories and in industry. That we are able to celebrate this 25th anniversary means that you have continually contributed to this journal with excellent science and new ideas. We take great pleasure in thanking you our authors, reviewers, supporters and readers for makingJAASsuch a successful journal.Searching the articles it becomes visible that from the beginning in 1986 until today a shift towards inductively coupled plasma-related research has taken place. ICP has become one of the central techniques studied and applied for trace elements and isotope ratio determinations. Therefore, for the next generation of authors it is a must to remember that the development of the ICP-MS by R. S. Houk and co-workers published in 1980 (R. S. Houk, V. A. Fassel, G. D. Flesch, H. J. Svec, A. L. Gray and C. E. Taylor,Anal. Chem.,1980,52(14), pp 2283–2289,DOI:10.1021/ac50064a012) is celebrating its 30th birthday also this year. Back in 1980 it may not have been predicted that this work would have such a tremendous impact and influence on elemental analysis and isotope ratio determinations. However, I can only speculate about this because in 1980 I was still in school and did not even know what an ICP was. Watch out for an article from Professor Houk later this year celebrating this seminal discovery.R. S. HoukRemember too that laser ablation inductively coupled plasma mass spectrometry is 25 years old this year (A. L. Gray,Analyst, 1985,110, 551–556,DOI:10.1039/AN9851000551) and searchingJAASyou can find a lot of contributions leading to the tremendous improvement in the understanding of this technique. A good portion of “open questions for further research” raised by Alan Gray in this paper have been successfully tackled, studied and published in our journal.Alan GrayThere are many interesting questions related to 25! What's the opinion of a 25 year old researcher about the future of atomic spectroscopy? Are you interested in what a well-known scientist in our field of research did 25 years ago? Or what Gary Hieftje predicts for atomic spectroscopy in the next 25 years? Well, most of you remember his most famous prediction about the future of AAS. We all know the math was correct. I can assure you that you will get a number of surprises during this 25th anniversary and I hope that these contributions will be stimulation for further submissions of high quality research toJAAS.Last year we indicated that we will work harder on involving geologists, biologists and other interdisciplinary research areas into our journal, since we are working with similar methods, techniques and equipment, and on similar fundamental questions. As a positive result of our activities in 2009 we received more manuscripts from these fields than the years before and we certainly hope that this positive trend will continue. Some of you might have noticed that reviewer comments on someJAASmanuscripts have been longer than the average 1.5 pages. Well, there are different traditions and differences between the communities and we should see this as a very positive chance to learn from each other.
