June 1964 Vol. I No. 6 Analytical Chemistry Chemical Analysis and the Analyst BY R. C. CHIRNSIDE (Hivst Reseavch Centre The Geneva1 Electric Co. Lid W e i i i b l e y :7I iddlesex) MR. CHIRNSIDE said that for too long the analytical chemist and his client had been content to believe that figures representing chemical composition could be transmuted by mathematical skill into a satisfying statement of chemical properties. ,4 new philosophy had been developed both in Britain and in the U.S.A. mainly in the context of industrial research. Some years ago E. B. Hughes had defined analysis as “the examination of a material to ascertain its composition its properties and its qualities.” This was now too restrictive as Liebhafsky said in his Fisher Award address-“I see modern analytical chemistry as the characterisation and control of materials.” These ideas were accepted in some of the more enlightened sections of industry but excluding that very necessary aspect of analysis called assaying even today far too much analysis went on in industry.Some analysts had become too absorbed in the mechanics of their task often enough set them by someone else and had failed to take a responsible interest in the delineation of problems to which analysis was expected to provide an answer. The analytical revolution of the last 20 years had seen the introduction of many wonderful new techniques and instruments but paradoxically the situation was fraught with danger. Unless there was some corresponding change in analytical thinking many of the new instrumental techniques might simply result in the production of a mass of indigestible and not very useful figures.If analysts did not abandon the 19th-century idea that 67 68 .4NL4LYTICAL CHEMISTRY CHEMICAL ANA4LYSIS AND THE ANLILYST ‘ P Y O C . S O C . %d. Clie?lZ. composition could be set out as an arbitrary list of elements or oxides other5 \voulc’i take over their ivork indeed they were already doing so. Demarcation disputes already existed here as well as in the craft unions. Some of the courses now offered in modern analytical chemistry were more concerned with the expertise of various new techniques of measurement than with analysis. Lundell’s dictum was still true today-“in applied analysis those operations which make the deter- mination possible are often more important than the determination itself.’’ In spite of the analytical revolution the prestige of analytical chemistry was still lower than might be expected.In the golden age of analytical chemistry the composition of much that went to make up the material world was “charted” by the analyst and a vast collection of basic information had been established. This had been seen as a research activity and the status of the analyst had been high. Later the emphasis had shifted to the commercial control or testing of materials to fix a price to meet a specification to comply with a regulation-and the objectives had seemed no longer to be so unambiguously scientific. The status of analysis and the analyst had declined even though the demands on his skill and his art were no less than before. It had not yet regained the prestige commensurate with its great and growing importance as a research service in industry and it was still difficult to combat the impression that those carrying out a services function were “somehow below the salt.” To regain prestige might require a drastic change of outlook on the part of the analyst himself and an educative process for those who require his services.If the analyst was to survive he would need to be on the alert to capture and harness and lay claim to any new technique that would help him to realise a new and wider conception of the objects and purpose of modern analytical chemistry-to accomplish the broad and indispensable functions of characterisation and control. Above all it was urgently necessary that this re-appraisal should be understood in academic circles so that it might be realised that it was the best and not the second-rate man that was needed for modern analytical work and that a worthwhile if demanding career was open to him.BIOLOGICAL METHODS GROUP AN Ordinary Meeting of the Group was held at 7 p.m. on Wednesday April BRth 1964 in the Meeting Room of the Chemical Society Burlington House London W.1.

June 19641 ANALYTICAL METHODS I N ARCHAEOLOGY 69 Physical Methods Applied to the Examination of Archaeological Remains MEETING OF THE PHYSICAL METHODS GROUP ON MARCH 2 4 ~ ~ 1964 The following are summaries of the papers presented by A . E. A. Werner M.A. M.Sc. I>.Phil. and E. T. Hall M.A. D.Phil. at the Meeting of the Physical Methods Group on Tuesday March 24th 1964 in London. A preliminary report appeared in the May issue of the Proceedings (p. 47). Analytical Methods in Archaeology BY A. E. A. WERNER (The Bvitish Museum Reseavch Labovatovy Londoii W.C. 1) DR. WERNER said that the problems facing the chemist engaged in the analysis of archaeological objects were different from those met with in the conventional research or industrial laboratory. The particular requirements of analytical techniques as applied to archaeology were influenced by the following five factors- Ty$e of analysis-There were two main categories namely (a) systematic analysis i.e.the analysis of large groups of antiquities to obtain analytical results of statistical significance relating to sources of origin or possible dating of antiquities and trade-routes of the con- temporary supply of a given material and ( b ) specific analysis i.e. the analysis of single objects or small groups of objects to help in solving particular problems including questions of authenticity. Nature of the antiquity-This determined the choice of the method of analysis which would depend on the permissible size of the sample that could be taken. Variety of avctiquities-The material to be analysed covered a very wide range including metals and their corrosion products ceramics glass etc.Sensitivity and accuracy-Depending upon the nature of the problem it might be necessary to determine the main elements present or to estimate the concentration of minor or trace impurities. This meant that several analytical techniques would have to be used to co\-cr the different composition ranges being examined. Nature of the problem-Close collaboration between the chemist and the archaeologist was essential to ensure that the problem was properly stated so that it could be solved in a realistic manner i.e. without unnecessary waste of effort on the part of the analyst. Analytical techniques were now being used on an extensive scale in archaeology and the following examples served to illustrate the value of analytical work in this field.The first was an example of systematic analysis carried out by Dr. Sayre a t the Rrookhaven National Laboratory in which he analysed over 200 fragments of ancient glass by using emission spectrography flame photometry and colorimetry. On the basis of the analyses he had concluded that at least five main categories of ancient glass could be recognised each having a characteristic chemical composition. The second example illustrated the use of analysis in a conservation problem namely that of so-called “weeping” glass i.e. certain types of glass objects that become covered with droplets of moisture when exposed under normal museum conditions. I t had been assumed that this phenomenon was associated with potash glasses but analysis of the droplets for sodium and potassium by using a flame photometer showed in fact that the glass was of the sodium type.The cure for “weeping” glass was to keep it under rigidly dry conditions below 42 per cent. relative humidity so that moisture could not extract a deliquescent mixture of sodium and potassium carbonates. While on the subject of glass Dr. Werner made reference to another interesting problem that had been solved by the analytical approach. This related to the Lycurgus Cup (recently acquired by the British Museum) which had a dull apple-green colour when viewed by reflected light and a clear purple colour by transmitted light. This phenomenon was undoubted- ly related to the composition of the glass. Qualitative emission spectrography had shown that besides the elements normally present in glass antimony silver and gold were also present as minor constituents.By using sensitive colorimetric and flame-photometric techniques especially adapted to this problem Mr. Chirnside had determined quantitativeljr the eight major elements present and also by using a special spectrographic technique he had 70 SPECTROGRAPHIC METHODS I N ARCHAEOMETRY [Proc. soc. Anal. C‘hevt. determined the concentration of gold as 0.003 to 0.005 per cent. of silver as 0.05 per cent. and antimony as 0.45 per cent. These results had been found to be in agreement with the composition required for making experimental glasses that duplicated the colour effect of the Lycurgus Cup. These glasses were being experimented with by Dr. Brill of the Corning Museum of Glass. A Romano-British numismatic problem had been solved by qualitative emission-spectro- graphic analysis (with about 5 pg of sample) when it had been shown that bronze coins had been deliberately given a thin coating of a silver - copper - tin alloy to simulate silver coins.The same technique (with about 1 mg of sample) had been used to distinguish for the first time by quantitative analysis between two groups of Chelsea porcelain. Also spectrographic analysis had been used to show that a figure alleged to be of Roman date was actually made of pure zinc-a material not available in Roman times. X-ray diffraction analysis was a technique that had been used to obtain interesting information about antiquities. It had been used for example to demonstrate a change in technique in the use of niello-a black decorative inlay on metal-that occurred in the 11th to 12th centuries and to determine the precise nature of the different minerals used in malting Babylonian cylinder seals of which there was an extremely large collection in the British Museum.Another striking example of the value of this technique was the work done by Mr. Rooksby on the elucidation of the nature of opacifying agents used in Western glass over a period of about 3,500 years. This had provided information that could be of value to the archaeologist as a possible means of dating pieces of glass in the absence of other evidence. In this context the speaker had found in the course of the examination of “jade” glass funerary objects of the T’ang period that calcium fluoride had been used as an opacifier whereas in the West this material was first used in the 19th century.Finally as an example of a contemporary material used by archaeologists to establish trade routes in ancient time the analysis of amber merited consideration. The problem here had been to distinguish between Baltic and non-Baltic ambers. Previous attempts based on relative content of succinic acid or appearance under ultraviolet light had given results of a dubious nature. Recently Professor Beck had shown that infrared-absorption spectroscopy could be used to solve this problem; he had found that the spectra of Baltic ambers could be clearly distinguished from those of non- Baltic ambers. Spectrographic Methods in Archacometry BY E. T. HALL ( T h e Research Labovatovy .fuv A ychaeologjf 6 Keble Izoad OxjoYd) DK. HALT said that the analytical laboratory that devoted its time to the investigation of museum and art objects must consider the various problems that it might be asked to tackle with aspects in mind quite different from the average chemical laboratory.Perhaps the most important point to be remembered was that in many instances no damage to the specimen was permissible although sometimes particularly with large objects some removal of sample might be allowed. If such sampling was permitted great care must be exercised when the material was removed since if an object had been buried for long periods the surface might be very different from the interior; hence a scraping was seldom of use except for the determina- tion of major elements and only a drilling into the body of the object would suffice. Even an apparently uncorroded noble metal would often exhibit “surface depletion” characteristics where one metal had been removed from the surface by leaching leaving the surface richer in the less soluble element.Besides the homogeneity of the object its shape and size might preclude the use of a particular technique but this again would depend on the accuracy of result required; perhaps only a qualitative result might be sufficient and when large numbers of specimens were to be analysed the use of a quick method was obviously desirable. The selection of technique wa5 also likely to be affected by a decision as to whether the major minor or trace elements were to be investigated. Although rnaiiy other methods were available and could be used for- analysing museum objects he said his lecture would be confined to the methods used in Oxford in his laboratory.These techniques consisted of optical-emission and X-ray spectroscopy neutron activation followed by y-ray spectroscopy /?-ray back-scattering X-ray diffraction and electron-probe June 19641 SPECTROGRAPHIC METHODS I N ARCHAEOMETRY 71 micro-analysis. Owing to some of the criteria outlined above they had found it necessary to design and construct their own apparatus ; although commercial equipment in some instances might be available there were nearly always drawbacks to its use mainly owing to the peculiarities of shape size and topography of the samples experienced. Optical-emission spectroscopy-If the removal of a small amount of material were permitted and the minor and trace elements were primarily required as quantitative results this technique was still supreme.Adequate accuracies of 15 per cent. of content were attain- able on a routine basis which is quite adequate for most purposes. Many hundreds of analyses of bronzes and ceramics were undertaken in the laboratory each year. Unfortunate- ly for the analysis of such small objects as coins and jewellery the taking of even minute samples was forbidden and the method was not applicable. The use of a low-energy radio- frequency excitation spark was also out of the question since only the first few contaminated microns of surface would be examined and this would give a totally unrepresentative answer. A’eutron activation-When a suitable neutron source such as a nuclear reactor was available this form of analysis had much to recommend it.After activation the resultant y-raj-s were analysed by pulse-height discrimination techniques. Suitable apparatus might be conveniently assembled in the laboratory. The great advantage of the technique was that owing to the penetrating power of the neutrons and also to the energy of the resultant y-rays the analysis would be representative of the entire object when the thickness was not more than a fekv millimetres. Moreover the sensitivity was good for most elements and it was totally non-destructive. In this context it was important that the neutron dose be kept within limits so that the resultant radioactivity did not prevent the object from being replaced in the museum within a reasonable time. The accurate analysis of coins was an obvious and existing application while the analysis of the trace constituents of ceramics was an area of activity where more work was required for full evaluation of the method.One important point to be noted was the fact that the size of “hole” with a suitable homogeneous neutron flux was in most reactors limited. Therefore it might not be possible to accommodate large whole ob j ec t s . P-ray backscattering-Chemical analysis in the true sense could not be accomplished by this teclinique. The ratio of forward to back-scattered rays between a P-ray source and an object would be related to the chemical nature of the surface of that object; the specimen that had the higher atomic- numbered elements in its surface would backscatter the greater proportion of P-rays. Many earl\- and late English porcelains could be differentiated by virtue of the fact that the early specimens had been lead-glazed whereas those made after a certain date were alkali-glazed.The lead glaze would backscatter the most P-rays. The apparatus was very portable and was suitable for museum use. S-ray $zmrescence spectrowzetry-At first consideration it appeared that this method of anal!-sis was superior to most others for archaeological non-destructive analysis. However on further examination they had found that there were serious drawbacks. The normal flat- crystal spectrometer “looked at” an area in excess of g-inch square ; moreover for comparison with standards this area should be flat. Again owing to the geometry of most spectrometers large objects could not be placed conveniently in the specimen holder even if this had been modified.I t must also be appreciated that owing to the small penetration of X-rays the surface of the object would contribute the greatest proportion of the fluorescence and hence the analysis might not be representative of the whole. To overcome the majority of these short- comings they had recently built a completely new type of point-source spectrometer that had a linear motion and a bent crystal. The area examined might be as small as 0.1-mm diameter. Very often an area of this size might be mechanically cleaned before analysis to obviate surface contamination or depletion effects. The present apparatus had been designed specifically for the analysis of paint pigments in situ. Electron-probe micro-analysis-By means of excitation with a beam of high-energy electrons only 1 p in diameter and analysis of the resultant X-rays special problems might be tackled. Minute inclusions in metals ceramics and lacquer had been examined in his labora- tory during investigations of ancient techniques. The analysis of multi-layer paint cross- sections had also been undertaken. Extremely small flakes of paint might be removed mounted in plastic and each layer identified; this would be quite impossible with any other ana1J.t ical procedure. I t was a method of comparing apparently similar objects. Moreover the sample volume was infinite. 73 MEMBERSHIP CHANGES LP'roc. SOC. Anal. Chenz.

June 19641 PUBLICATIONS RECEIVED 73 International Union of Pure and Applied Chemistry BUREAU AND EXECUTIVE MEETING IN BASLE MARCH 1964 BASLE was the venue of the recent meetings of the Bureau and Executive Committeeof the International Union of Pure and Applied Chemistry. I.U.P.A.C. is a voluntary non-political and non-profit-making organisation that is concerned with the promotion of a permanent co-operation between the chemists of its member countries (2) by providing through congresses and symposia a forum for the discussion by specialists of important and actively developing branches of chemistry (ii) by considering those problems requiring international agreement such as nomen- clature standardisation etc. and which limit the ability of scientists to com- municate precisely with one another and (2';;) by co-operating with other international agencies whose activities involve problems of a chemical nature.74 [Proc. SOC. AnaZ. Cheulz. I.U.P.A.C. is governed by a Council of 138 delegates from its 38 member countries which because of its size meets every two years only. Between Council meetings a smaller Bureau of 23 persons is entrusted with the conduct of the Union’s business; between Bureau meetings an Executive Committee of 8 members controls Union affairs on behalf of the Bureau either by correspondence or in person. The Union’s President is Lord Todd of the United Kingdom. The working units of the Union known as Commissions are small groups of leading experts constituted for specific scientific purposes. The Commissions conduct their business by correspondence and at occasional meetings.The Commissions involve more than 400 scientists through whose voluntary efforts such matters as the nomenclature of organic and inorganic compounds or the fixing of the scale of atomic weights are established. Their recommendations which have the broadest and most important implications in the practice of chemistry must be accepted by the full Council before promulgation. The last meetings of the Bureau and Executive Committee organised by the Secretary- General Dr. R. Morf in the premises of F. Hoffman-La Roche & Co. Ltd. Basle were convened to deal with the many important problems of policv that have been generated by the rapid growth both of the practice of chemistry throughout the world and of the Union’s own activity. Matters of such importance as the programme of future scientific activities the nature of collaboration with other international agencies and chemical industry throughout the world the problems of methods and standards of the teaching of chemistry and the way in which the results of this exercise can be applied to help developing nations and the publication of the results of its scientific and more formal deliberations have been debated with vigour and profit throughout the week.Members of the Bureau have enjoyed the generous hospitality of their Swiss colleagues at the end of each day’s meetings. Some of the results of these meetings will be of interest to chemists generally. The Union has been endeavouring to establish closer liaison with chemical industry. The President Lord Todd reported that his international committee of leaders of chemical industry had drawn attention to several matters that it felt should be considered by the Union including- the teaching of chemistry particularly in relation to the increasing nccds of thc industry for scientists and technologists and (zi) the serious problem of documentation exchange and retrieval of scientific information.4 proposal for a congress a t which topics of industrial interest should be presented to the public was endorsed. INTERNATIONAL UNION OF PURE AND APPLIED c HEMISTRY (i) The increasing demand from United Nations agencies and other international bodies for advice and co-operation on matters of chemical content was recognised and the respon- sibility for co-operation and assistance was accepted by the establishment of a mechanism within the Union by which such requests could be met.A strong international committee together with correspondents in member countries was established to examine the problem of teaching of chemistry at all levels to survey the practices in member countries and to make proposals to U.N.E.S.C.O. suitable for imple- mentation in the developing countries of the world with particular reference to the state of development of primary secondary and tertiary education in these countries. The question of sponsorship of scientific meetings is of special concern to the Union which encourages the development of significant areas of chemical science by the sponsorship and initiation of congresses and symposia throughout the world. Decisions were taken to sponsor the following meetings- (i) (ii) (iii) ( i ~ ) International Symposium on Organic Photochemistry in Strasbourg France ; International Symposium on Microchemical Techniques in Pennsylvania C.S.A. ; Eighth European Molecular Spectroscopy Meeting in Copenhagen Denmark; and jointly with the International Union of Pure and Applied Physics a Symposium on the Physics and Chemistry of Solid Surfaces in Providence U.S.A. The main lectures at these symposia will be published in Pure and Applied Chemistry the Union’s journal in the same way that has proved so successful in recent years. The next business session of the Union the XXIIIrd Conference will be held in Paris during July 1965 and the XXth Congress of Pure and Applied Chemistry in Moscow also in July 1965,
