Analyst, August 1995, Vol. 120 103N Book Reviews Multivariate Analysis in Practice By K. Esbensen, S. Schonkopf and T. Midtgaard. Pp. 362. CAM0 AS. 1994. Price f199. ISBN 82-993330-0-8 This book is a tutorial training package for multivariate analysis based on the Unscrambler software. This software is a package for multivariate analysis by the application of chemometric procedures of PCA (principal components analysis), PCR (principal components regression) and PLS (partial least squares). The software is currently MS-DOS based (Version 5.52 at present) and not readily approachable by non-expert users although it is recognized by many spectroscopists as being the de fact0 industry standard. However, it must be said that whilst its power is undisputed it does not enjoy a reputation for ease of use.A Microsoft Windows version of the program is currently under develop- ment and should be available towards the end of 1995. This tutorial package consisting of a 362 page book and a demonstration version of the Unscrambler software is an attempt to bridge the knowledge gap for those who would like to use these powerful procedures but lack the current expertise. The software provided is a fully featured version of Unscrambler but will only run the data sets provided. The machine chosen to run the demonstration software on had a Pentium 90 MHz processor and 32 MB of RAM with MS-DOS 6.22 running multiple configurations. Loading the software was not straightforward and the instructions could have been clearer. In the event, it was necessary to remove emm386.exe entirely from the CONFIG.SYS file as well as replacing the Norwegian keyboard set up in order to get the program to run successfully.Once done, however, it per- formed very well. There is an important typographical error on page 2 of the manual; it should read BUFFERS = 30 in the first line. As the graphical output is most important, the ease of printing is not Straightforward although adequate copy was available from my Laserjet 4Plus printer using HPSCREEN or GRAPHICS.COM. Alternatives are via Postscript or HPGL to file or direct to a plotter. Such problems will disappear when the Windows version of the software becomes available. The book itself is much more user friendly than the Unscrambler user manual and consists of 14 chapters and some appendices. It is a pity that the index in the book contains errors necessitating an inserted correction sheet.‘The authors have taken a great deal of time and effort in explaining the basis of PCA and its position in multivariate analysis without recourse to matrix algebra.’ The authors have taken a great deal of time and effort in explaining the basis of PCA and its position in multivariate analysis without recourse to matrix algebra in the first five chapters. Careful explanation of the meaning of terms is given, e.g., scores, loadings, scaling, etc., which can be very daunting for those meeting them for the first time. These explanations are accompanied by exercises with the data sets provided which allow the user to see for themselves what is happening.The program itself has been much improved over the years but is still slightly clumsy and command-driven especially for those more used to the Windows environment. This is especially true of the quality of graphics offered and the ability to incorporate them into word processing or presentation packages. This said, however, the program is much easier to use than it was, especially for the novice. It is apparent that the book is intended really as part of a training course as it asks questions to test understanding at key points but does not always provide the answers or output directly. This is particularly important for those who intend to use it as a stand-alone package for training purposes and the authors would do well to consider this aspect in future editions.Having covered PCA in some detail, the book moves on to multivariate modelling and PCR. Having discussed regression and the weaknesses of PCR, the book moves onto the heart of Unscrambler, PLS. The authors do well to keep the more formal mathematical algorithms to the Appendices and to concentrate on the pictorial representations and actual exam- ples because PLS is not the most easily digested topic. The comparison of PCR and PLS by example is most helpful. Chapters 7 to 10 are concerned with the methods of assessing the validity of models with real data sets and is very well done. At this level of sophistication there are fewer areas where one can say there is a right answer! Discussion topics include outlier detection and rejection, need for data pre- treatment, errors in data and many more, together with strategies for dealing with them.Chapter 12 is a brief introduction to experimental design which is sufficient with the scope of the tutorial but needs to be supplemented with more substantial works. The final chapter is a summary of how to choose methods for multivariate calibrations and is a distillation of the conclusions from throughout the book. If anyone likes the look of the mathematical appendices, a thorough explanation is available in ‘Multivariate Calibration’ by Martens and Naes, John Wiley, 1989. In conclusion, I think that this package provides a much more user-friendly approach to multivariate analysis using the power of Unscrambler than hitherto available. It provides the opportunity for those who have not been able to try the program before (the full version is expensive) and to get a feel for modelling real data sets.Notwithstanding the slight drawbacks discussed above, this product addresses a much needed training requirement in the application of multivariate methods to real-world problems. Chris Burgess Barnard Castle Co. Durham, UK ~~~ Derivative Spectrophotometry By Gerhard Talsky. Pp. xiv + 228. VCH. 1994. Price DM248.00. ISBN 3-527-28294-7. In recent years there has been an increase in the number of papers dealing with derivative spectrophotometry . Although currently in vogue, their origin dates back to the early twenties, when Lord Rutherford suggested the use of the first derivative curve in mass spectrometric studies. The idea was taken up by Singleton and Collier in the fifties and a new technique was born.The lack of suitable equipment held back its general development, but in recent years, advances in electronics have led to the introduction of spectrophotometers with facilities for low and higher order plotting of spectropho- tometric data. Amongst the leaders in the exploitation of low and higher order derivative spectrophotometry is the author of this monograph. The extent of his contributions to the subject is104N Analyst, August 1995, Vol. 120 apparent in the list of his publications given in an appendix. The text itself begins with a brief introduction to the subject, this is followed by chapters dealing with the theoretical aspects ‘many hitherto intractable analytical problems may be solved by the use of derivative spectro- photometry’. of derivative spectrophotometry, instrumentation enabling derivative curves to be generated, and an account of the author’s practical experience over a sixteen year period working with the technique.The final chapter provides in tabular form some 500 examples of applications selected from an ever-expanding literature on the subject. Ample evidence is presented to show that many hitherto intractable analytical problems may be solved by the use of derivative spectrophotometry . Generally, third, fourth and even higher order spectra are used, as an examination of the applications chapter readily shows. Many existing spectropho- tometric methods can be greatly improved with regard to both sensitivity and selectivity by the use of the derivative technique, and it requires no great foresight to predict an enormous growth in publications on the subject as the instrumentation becomes more accessible to practising analysts in a wide range of disciplines.This, the first monograph on derivative spectrophotometry , provides a most welcome addition to the library of absorption spectrophotometry. Although much of the text is based on the author’s work and experience, it is, nevertheless, a volume that deserves a wide readership amongst analytical scientists. W. I. Stephen Aberdeen, UK ~~~ ~~~~~ ~~~~~ Statistical Methods for Groundwater Monitoring By Robert D. Gibbons. Pp. xii + 286. Price f48.00; $80.50. ISBN 0-471-58707-9. In order to properly identify environmental contamination requiring costly clean-up measures, it is essential that monitor- ing data be evaluated using sound statistical procedures.There is considerable controversy as to the best statistical methods to apply, and often there are regulatory requirements to use procedures which are clearly not the most appropriate from a statistical perspective. This book is a thought-provok- ing presentation of the issues involved in evaluating statistical methods and their application to sound environmental deci- sion-making . In all environmental monitoring, the fundamental challenge is to establish the uncontaminated, natural background level of a toxic elementkompound and then to compare repeated future measurements of the same toxin to that level in order to determine whether or not contamination has been introduced.Yet the number of toxins to be monitored is large and the natural occurrence level of each can be highly variable andor near method detection limits. Additionally, the number of measurements needed to establish both initial background and future occurrence levels rapidly become prohibitively expensive. As a result, monitoring programmes are generally based on fewer measurements than ideal. The number of comparisons made significantly impact the false positive and negative rates experienced when monitoring a site. False negatives, the failure to detect contaminants which are present, may be the greater environmental concern but regulation ignores the possibility of such occurrences. Regulation, on the other hand, demands the same clean-up regardless of whether detection represents true occurrences of contamination or a false positive, detection when no contami- nant is present. Experimental designs must therefore consider both false positive and false negative rates simultaneously; however, either one is reduced only by increasing the other.The author addresses all of these issues throughout his presentation of statistical methods appropriate to environ- mental monitoring programmes and decision-making based on them. ‘a thought-provoking presentation of the issues involved in evaluating statistical methods and their application to sound environmental decisionmaking,’ He presents a review of statistical topics bearing on environmental monitoring programmes and applies these to specific groundwater monitoring data sets, to illustrate how variable the conclusions can be as a function of the statistical model employed.The discussion centres on programmes which monitor groundwater for contamination due to nearby waste disposal facilities. It further focuses on the multiple comparisons involved when multiple sites are sampled at one waste site, and many potential contaminants, rather than just one, are monitored. The author first examines parametric prediction limits, based on the assumption that the monitoring data is normally distributed. The most appropriate parametric prediction intervals are those calculated, for a fixed site-wide false positive rate (e.g., 5%). One approach is to calculate a prediction interval having a 5% site-wide, false positive rate that will include all future measurements.This, however, frequently results in an unacceptable false negative rate. The strategy that balances false positive and false negative rates employs both an initial monitoring sample set, and verification resampling if any of the initial samples exceed regulatory limits; the site is established to exceed limits only if the resampling confirms the initial determination. A number of less-than-detection-limit results occur in many data sets, and other factors also cause many environmental data sets to exhibit distributions other than a normal distribution. Therefore non-parametric prediction intervals are often better suited than parametric ones to the evaluation of data from environmental monitoring programmes.After presenting several examples of determining non-parametric prediction intervals, the tolerance interval is introduced. Recommendations are made for using a combination of tolerance and prediction intervals for initial testing and verification resampling data sets, to obtain the soundest decision in the most efficient manner. The author comments, however, that regulation currently prohibits that approach. Also discussed is the calculation of method detection limits and practical quantitation limits. This topic is of considerable importance, since in monitoring situations, false negative conclusions are of greater concern than false positive conclusions, even though traditional detection limit estimators protect only against false positive conclusions. This discussion continues in a later chapter on censored data sets, in which the author points out that properly estimating the mean and variance of a censored data set, which is of the critical importance in determining the level of contaminant actually present in either the site background or future site sample. A number of additional topics are also presented in a manner that is statistically rigorous, without overwhelming the environmental and analytical chemists. These chemists are responsible for generating the data that is being evaluated by the environmental regulatory community, and should there- fore become as involved in the quality of the data evaluation and interpretation as they are in producing the data. If they were, the misinterpretation of environmental data which Dr. Gibbons describes so well, can be greatly diminished. Jean S .

Analyst, August 1995, Vol. 120 111N Conference Report SCANNING ‘95-The Seventh Annual International Scientific Meeting Sponsored by the Foundation for Advances in Medicine and Science, Monterey, CA, USA, March 28-31 1995 The Foundation for Advances in Medicine and Science (FAMS) , The publisher of the periodical Scanning, Inter- national Journal of Scanning Microscopies, organizes a meeting and an exhibition once a year, in spring, usually at a well chosen location in the USA. This year’s scene was marvellous, the dreamy coastal resort of Monterey, just a couple of minutes walk from the harbours and wharves. Indeed, the incessant calling *of sealions could be heard through open windows in the hotel. Tuesday was a preliminary day to the conference when a series of parallel one-day workshops were held as a precursor to the meeting proper.Of the four short courses my attention was divided between ‘SEM and Microelectronics’ and a ‘Manufacturers Confocal Workshop’. Both were well atten- ded. At the latter, recent commercial developments were presented and closely questioned by the scientific attendees. In the evening a reception for the 400 delegates was held in the hotel’s foyer and was an informal chance to gather and meet others attending the conference. The main meeting began on Wednesday as well as an additional two whole day workshops. Once again a multi- plicity of interests was represented in the three concurrent sessions. The presentations to which I went were very good. In the morning I attended the session on ‘Monte Carlo Simula- tions in Scanning Microscopy and Electron Beam Litho- graphy’ which examined the use of Monte Carlo techniques to study electron-specimen interactions that are so fundamental to electron microscopy as a whole.The heavy reliance on raw computing power that this study needs was emphasized by a passing comment which left the other players aghast, from Jeremiah Lowney (NIST) which was that one series of calculations had taken 10 hours on a Kray computer! Nevertheless, much useful work is being done with affordable and ubiquitous DIY PCs and work stations. This session brought together many of the leading authorities (Raynald Gauvin, Dale Newbury, and David Joy) who presented papep on contrast at low voltages; the progress of an X-ray database; and electron stopping power, respectively.During the afternoon there was an interesting session on ‘Low-temperature Scanning Electron Microscopy’ where a presentation on ‘Three Dimensional Characterization of Snow’ by Wergin et al. particularly caught my eye and ear. The paper amply illustrated the extent to which an investigator must go in the study of his selected field, as the samples of snow had been collected during the depths of winter from the Maryland countryside. Their beauty was sufficent to warrant gasps of amazement from the audience. Thursday had an addition to the published conference programme with a session on ‘Computers in Microscopy’. A lecture theatre was filled with PCs to allow delegates to get to grips with a variety of software some of which was being informally presented, some personally developed and some commercially available.Particularly useful were programs to simulate electron scattering using Monte Carlo techniques (SimFlight), another demonstrated software to aid newcomers to understand and self test the basics of electron microscopy (Griffin, University of Western Australia). The afternoon saw a particularly interesting session on ‘Environmental SEM’ examining this rapidly expanding area where wet or hydrated samples may still be examined at high magnification and good resolution. The paper ‘A Newcomer to the Field’ by Dale Newbury (NIST, who is far from a newcomer to electron microscopy and microanalysis) exposed the problems that might be found in coming into this field of endeavour. The more technically minded in the audience were enlightened with a paper on Detector Strategies (Griffin, UWA) which was liberally intermixed with slides of trees found by the presenter in outback Australia.A late evening session unfortunately was not well attended. On the Friday morning, the final sessions of the meeting were held, one of which was on ‘Microcharacterization by X-ray and Electron Diffraction’. This was not a wind-down session as is sometimes the case but rather contained a series of exceptional papers. Brian York (IBM, San Jose) gave a paper on the methods of production and uses of a finely collimated beam of X-rays to give diffraction patterns from micron volumes of sample. David Dingley (currently on sabbatical from the University of Bristol) gave a very polished presentation on a material’s grain structure by its electron backscattering pattern (EBSP).This was followed after the break by John Sutcliff (GE Corporation) with an intriguing paper, the commercial uses of EBSP where hundreds of samples were mounted for a continuous run of literally a million selected target areas. Throughout the meeting an excellent commerical exhibition was held which could only be faulted as it clashed with the main meeting sessions, but to make sure of a good attendance at the end of each day, a happy hour with the drinks served in the exhibition hall was an attractive feature. As is usual at such events it was not all work and no play. I was able to look at the local countryside by travelling the ‘17 Mile Scenic Drive. The main attraction of this drive was to see sea otters playing close to the beach. So ended a meeting which was exciting on account of the science presented, the enthusiasm of the well informed audience and naturally by the local environment in which the meeting was held. P. G. T.
