Division of Analytical Chemistry Completes 20 Years of Activity Resurgence of analyticat chemistry in the past two decades has been paralleled by the formation and growth of the Division of Analytical Chemistry, American Chemical Society. Probably the most characteristic feature of the expansion of both in recent years is a widespread interest in instrumentation of analysis T h e American Chemical Society's 135th national meeting a t Boston this month will mark completion of a 20-year period during which members interested in analytical chemistry have met as a separate division. Having first met officially in 1939 as the Division of Microchemistry, the group merged in the following year with the Analytical Sectionwhich separated from the Division of Physical and Inorganic chemietry-and was renamed the Division of Analytical and Microchemistry. I n 1949 the name was shortened to the Division of Analytical Chemis-
try, its present name. Since ita inception two decades ago, the division has grown steadily, both in numbers and in stature. Membership increased from 122 in 1940 to 2735 in 1958. The value of the contributions made to the profession of analytical chemistry by division members cannot, of course, be measured quantitatively ; but i t is interesting to note the parallel growth of analytical chemistry as a professional field in the United States, and of the division itself. Development and growth in a field are engendered by external factors
-economic, military, and social. But the growth of the field indicates the need for group action, group action advances the field, and those organiza Lions dependent upon activities 1i.ithin the field come to support the group. All benefit to an extent far greater than the needs of the moment dictate. So it goes with the Division of Analytic &l Chemistry. One cannot peg a particular period and say without qualification that the profession of analytical chemistry began a t t h s t time. Probably the first attempt t o put analytical chemistry

This inspired efforts toward improved methods of analysis, and rcqulted in bringing new light on hydrolysis, arid-basis titrations, formation of complex salts, and other fundamental phenomena ( 4 ) . N o t only were existing methods improred, but new fields of research were initiated. Subxquently came application of
physiral and physico-chemical methods to the solution of analytical problems. Microanalytical Chemistry Develops
Until about the end of t h e 19th century interest in analysis continued to be centered mainly in the composition of inorganic matter. But then methods of organic synthesis increasingly became the preoccupation of chemists throughout the vorld, and the general feeling

analyse” appeared in 1930, many European industrial laboratories had adopted quantitative organic niicroanalytical methods for some routine procedures. Previously, by 1922, enough interest had been aroused t o bring about publication of a journal devoted entirely to papers on microchemistry. Emil Haim and Co., Leipzig and Vienna, started publication of Milcrochemie, which was edited by Emich, Pregl, Lieb, and other well known microchemists. Microchemistry was introduced in the United States during the late twenties and early thirties, partly through the efforts of former students of Emich and Pregl. The trend of its growth, both here and abroad, was rather clearly reflected in the increase in the number of papers on microchemistry appearing over the years. During the tenyear period, 1890-1900, eight papers were published, dealing largely with the use of the microscope. Between 1911 and 1919, 102 papers on microchemistry were published. The period from 1926 t o 1930 saw the appearance of 440. I n the single year 1931, there came 850. And in the year 1934, about 2000 papers on microchemistry appeared in the various journals ( 3 ) . Inevitably, such vastly increased interest led to special symposia on various phases of the subject. The first of these t o be sponsored within the American Chemical Society was held a t the 89th national meeting in New York City, September 1935. But this expansion of interest in microchemical methods, while a phenomenon in itself, nevertheless served as an accompaniment to a steady growth of interest in other aspects of analytical chemistry. Rapid Growth in Instrumental Methods
Interwoven with the growth of analytical chemistry is the rapid development of instrumental methods of analysis, especially in the post-Vorld War I1 period. This has been characterized by a tendency t o use the terms “analytical instruments” and “ins truinental analysis” each in a different context.

Back Two Decades Growth of tlie field of analytical chemistry indicated the need for group action in the form of technical programs and publications. jI’ithin the Ainerican Chemical Society, this resulted in formation of the Aiicrochemical Section of the Division of Physical and Inorganic Chemistry. Under the leadership of A. A. Benedetti-Pichler and F. Schneider, this section sponsored a symposium 011 microclieinical inetliods a t the Kansas City ACS meeting in 1936.

mented on the possibility t h a t division rolls could be increased to 1000 members if current members would serve informally as boosters of tlie organization. B y the time tlie M a y issue appeared, he was able t o state editorially t h a t membership had increased to 700, and by the end of tlie year the number had passed tlie hoped-for 1000 and gone on to 1224, Membership dropped off again ?nl the following two years, reaching a, trough in 1951 a t 701 persons. Possibly this could be attributed indi~ e c t l yto a dip in industrial activity during t h a t period as well as uncertainties produced by the Korean si’cuation. At any rate, gains have been shown from 1961 t o the present, the biggest jump taking place in 1955 when membership of 2115 persons was almost exactly double that of the previous year. Although the Division of Analytical Chemistry is the fourth youngest of the society, its 2735 members make it the third largest among the total of 22. Clearly, its growth has been remarkable, to say the least. TT’hat are the attractions which make membership desirabIe t o the individual? There are many ways in which the analytical chemist can keep up with developments in liis profession. Published papers and reports, review courses, and round table discussions all have their place in the scheme of things. But the latest information is usually given out a t professional meetings. If unrestricted in nature, as most fundamental work shouId be, tlie latest accomplishments are usually announced by scientlsts a t a meeting of his peers.

sponsored 46 symposia on various topics a t its national meetings alone. The analytical chemist interested in methods of instrumental analysis would have found several symposia of pertinent value during t h a t period, for example: chemical analysis by means of infrared spectrophotometry ; polarographic methods; advances in gas chromatography. For those interested in nuclear analysis: nucleonics and tracer techniques in analytical
chemistry ; radiochemical analysis. For the microchemist: microchemistry and the petroleum industry; microchemistry. For the educator: problems in the teaching of instrumental analysis; teaching organic analysis. I n addition, thert: mere inany other symposia, some of a generalized nature and others geared to more specialized aspects of the profession. These titles alone are indicative of the leacership of the
division in presenting resumes of the latest developments of current interest t o the analytical chemist. Interesting to note is the fact that,, of these symposia, exactly half, 23, were jointly sponsored with other divisions and organizations. Surely this is a reflection of the extent to which chemical analysis cuts across every branch of chemical endeavor. I n addition t o symp,osia presented a t the national meetings, many other papers covering these and other topics were given a t general sessions of the divisional meetings. Summer Symposia Started in 1948
The desire t o discuss selected topics a t a more leisurely pace led t o the Summer Symposium series. These were initiated under joint sponsorship of the Division of Analytical Chemistry and AXALYTICAL CHEMISTRY in 1948. The goal is to present specialized topics which can be covered in a short period and in surroundings conducive to learned discussion. The first of these, in 1948, was concerned with nucleonics and analytical chemistry. Typical of those t h a t followed were: standards and standard methods ; analytical chemistry of less familiar elements; and analytical chemistry of fused media. We have seen how t h e growth of analytical chemistry led t o organization of the Division of Analytical Chemistry. We also have seen how the group has helped advance the field of analytical chemistry. It may be of interest t o observe how those organizations dependent upon progress in the field support the work of the division. Nobody need be reminded t h a t underwriting expenses of personnel attending meetings is a major form of support by industrial firms, universities and colleges, and government agencies. Again, nobody need be reminded t h a t permission t o report research results is a major form of support.

potential members of the profession and its associated fields? Within the Division of Analytical Chemistry there have been three outstanding contributions of this type. The Fisher Scientific Co. established its Fisher Award in Analytical Chemistry in 1947 for the purpose of recognizing and encouraging outstanding contributions to the science of pure and applied analytical chemistry. This consists of a cash grant of $1000 plus an additional amount for expenses incurred by the recipient in traveling to the meeting a t which the award is presented. The winner also receives an etching. I n 1953, Beckman Instruments, Inc., established the Beckman Award in Chemical Instrumentation. This is given for outstanding achievement in developing new instruments for chemical analysis and in application of analytical instruments for chemical process measurement and control. This award also consists of $1000 cash plus an amount for travel expenses to the presentation meeting. The winner also receives a scroll. Both awards are presented annually. The third award sponsored by an industrial firm was the ' Merck Graduate Fellowship in Analytical Chemistry, granted annually with a stipend of $2500 during the years 1949 t o 1957, inclusive. These were sponsored by Merck and Co. Further details of this award and its winners appear elsewhere in this rep or t. I n such ways are the trends of analytical chemistry reflected in the growth of the division. But what of the future? Although i t is difficult t o make predictions, suffice it to say that the profession of analytical chemistry, the Division of Analytical Chemistry, and the benefits accruing t o those whose activities are dependent on analytical chemistry should all advance and increase as man continues t o probe technological frontiers.

Colorimetric De te rmi nation of Siliceous Atmospheric Contaminants. Particulate silica and silicates are collected on membrane filters, dissolved in hydrofluoric acid, and determined colorimetrically as yellow silicomolybdate or as molybdenum blue after reduction with 1 -amino-2-naphthol-4-sulfonic acid. The dual sensitivity obtained by the use of the two colors permits accurate analyses in the relatively large range of 1 microgram to 2.5 milligrams without the necessity of taking an aliquot. The small air volumes required are easily sampled with hand-operated equipment.
A Method for D e t e r m h l n g Aero-Al l ergen Concentrations W i t h The Molecular Filter Membrane. An apparatus, consisting of 6 sampling heads containing MF filter discs, i:;described for obtaining accurately the diurnal variation of airborne pollens. A clock operatec' switch automatically connects each head in turn to a vacuum manifold for a 30-minute period eaih 4 hours thus obtaining a 24-hour sampling profile. The MF discs are then rendered transparent and stained for microscopic examination of the collected pollen. Cryrt, S.; Gurne;,, C. W.; and Honran, W.
