ACS Centennial Meeting New York City April 4 to 9, 1976 The American Chemical Society w i l l celebrate its Centennial w i t h a se ries of special Centennial events i n ad dition to the scientific and governing sessions. Monday afternoon has been set aside for a ceremonial session which will be held in the Grand Ball room of the New York H i l t o n . Other special Society-wide events include a time capsule ceremony and the 100th anniversary reception and banquet. I n observance of the ACS Centenni al, the Analytical Chemistry Division has planned an especially strong tech nical program w i t h 33 symposia ses sions consisting of nearly 150 papers. A key part of the program is the Wednesday symposia sessions which will focus on the past 100 years in ana lytical chemistry. Galen Ewing, pre siding at these sessions, is coeditor w i t h Herbert A. Laitinen, editor of ANALYTICAL CHEMISTRY, of a planned book entitled "Centennial History of Analytical Chemistry". Other symposia planned by the D i v i sion include two award symposia, sev eral joint symposia with other divi sions, and symposia on validation of the measurement process, develop ments in thermal analysis, energy and a clean environment, chemical separa tions, plasmas for elemental analysis and elements in managing an analyti cal laboratory. Joint symposia topics include advances in characterization of metal and polymer surfaces (eight sessions), impact of microelectronics on chromatographic automation (two sessions), and new approaches to the routine determination of serum en zymes (three sessions). The most ambitious of the above symposia deals with the characteriza tion of metal and polymer surfaces
and includes 41 papers i n eight ses sions w i t h plenary lecturers introduc ing each session devoted to a separate technique used in surface analysis. The ACS Award Symposia on Ana lytical Chemistry and Chromatogra phy honor the 1976 winners of these awards: H . V. Malmstadt and James S. Fritz, respectively. Sessions of the Analytical Chemistry Award (spon sored by Fisher Scientific Co.) sympo sium deal w i t h analytical and clinical methodology, a new era in analytical chemistry, chemical instrumentation, and analytical spectroscopy. H . V. Malmstadt will discuss "Super Ana lytical Robots". I n the Chromatogra phy Award (sponsored by Supelco, Inc.) symposium, J. S. Fritz will talk on "Concentration of Solutes from Aqueous Solution". A l l the above symposia will take place at the New Y o r k H i l t o n except for the symposium on metal and poly mer surfaces which w i l l be held at the Statler-Hilton. The New York H i l t o n is also the site for the exposition which will be open A p r i l 5 to 8. Analytical chemistry, especially i n its applied aspects, is well represented in the programs of other divisions. Particularly notable are the symposia in the Division of Environmental Chemistry devoted to air and water pollution. Included are sessions deal ing with the measurement of atmo spheric aerosols, instrumental analysis of water pollutants, and the measure ment of gaseous pollutants in air. Preregistration forms, housing i n formation, and details of the ceremo nial events appear i n the Jan. 5, 1976, issue of Chem. Eng. News. The com plete technical program for the entire meeting w i l l appear in the Feb. 23 issue. The detailed technical program which follows includes all the Analyti cal Division sessions including those jointly sponsored.

BUCHLER
Fractomette Alpha 200 Buchler's new fraction collector has much more going for it than a pretty new face. It is equipped with standard features you just can't find on other fraction collectors. The Alpha 200 is complete for time, drop and volume modes of collection. It has a 200 tube capacity, yet measures less than 114 sq. feet and will fit into an ordinary household refrigerator. Reliable 100% solid state circuitry, a lift-off collection platform, an electronic digital display and "LiquiFuse" — a unique overflow detection device — are some of the new features. If we didn't think this was the best fraction collector on the market, we wouldn't have made it. We believe you'll share our enthusiasm when you learn more about the Alpha 200. Write Today!

Liquid Chromatography in Insecticide Studies
High-pressure liquid chromatography is being used to study the fate of new insecticides i n aquatic environments. A t the Mosquito Control Laboratory i n Fresno, Calif., a field station of the Department of Entomological Sciences at the University of California at Berkeley, chemical, biological, and cultural approaches are all being used in mosquito control. Charles Schaefer, the laboratory's director, is reported to believe that of the three approaches being used, chemical control still holds the greatest promise. New insecticides now being made are markedly different from earlier ones such as the chlorinated hydrocarbons and organophosphates. New insecticides are more effective, more selective, and more expensive. I n all of the studies w i t h new chemical insecticides, samples of soil, water, and vege-

Eugene P. Scheide and John K. Taylor, chemists at the National Bureau of Standards, have developed a mercury monitoring device for use in the workplace. The device measures mercury concentrations at the ppb level and gives the total accumulated dosage of mercury over a workday, rather than the concentrations of mercury a worker is exposed to at a given time. Use of the NBS monitor should help insure that NIOSH standards are being met. Heart of the device is a quartz crystal which vibrates at a certain known frequency (piezoelectric crystal). The crystal is coated with a thin layer of gold which adsorbs mercury present in the workplace. The amount of mercury adsorbed by the gold over a day is determined by measuring the change in frequency of the crystal. The crystal itself is enclosed in a glass holder and is sealed to it at the base with epoxy cement. The device is worn by a worker along with a miniature air pump which is worn in a pocket or around the worker's waist

Cancer Detection by Laser Light Scattering
tation are analyzed for chemical residues immediately after the insecticide is used and at regular intervals thereafter for several weeks. Promising chemicals are tested for several years to assess the effects of repeated application. The testing procedures for soil or water involve extracting the sample w i t h methyl chloride, drying the extract over sodium sulfate, concentrating the sample, and then analyzing w i t h the Varian 8500 liquid chromatograph. Accurate determinations of residues at the ppb level are required. According to Schaefer, the most promising chemicals being studied have unique modes of action. Thompson-Haywar'd D i m i l i n is one. Others include the juvenile-hormone analogues, which upset the development of insect larvae, and a synthetic analogue of pyrethrin, the natural insecticide that occurs i n the plant Pyrethrum.
Scientists at Los Alamos Scientific Laboratory are working on a new cancer cell identification system. The laser method of analyzing particles by using light scattering patterns enables a distinction to be made between the light patterns of normal and abnormal cells. The method can also be used to sort different kinds of white blood cells. This suggests the possibility of broader medical applications. The fact that most living cells and microorganisms can be distinguished by laser scattering patterns without killing them provides the basis for possible advances i n this field. The equipment used in these studies is made by Science Spectrum and was designed by its president, Philip J. Wyatt. Other areas of research include vitam i n potency analysis, determination of antibiotic residues i n various food products, and serum level monitors for cancer chemotherapy.

Stephen J. Swarin and Andrew M . Wims, specialists i n organic analysis and polymer characterization at General Motors Research Laboratory, have developed a fast, accurate procedure for analyzing compounded rubber materials used i n automotive parts. The procedure, based on thermogravimetry, permits both the qualitative and quantitative analysis of many rubber compositions. Rubber compositions analyzed successfully at G M are: oil-extended ethylene-propylene-diene-monomer ( E P D M ) rubbers used i n bumper guards, weather stripping, radiator hoses, and engine and body mounts and plasticized nutrilebutadiene rubbers ( N B R ) used i n seals, O-rings, and hose liners. The average 1975 U.S.-made car required about 3 lb of E P D M and 3.6 lb of N B R . W i t h a single experiment the
percentage of extender oil or plasticizers contained i n a sample, along w i t h the percentage of rubber, carbon black, graphite, and mineral fillers, can be determined. The new procedure takes about an hour, i n sharp contrast to the conventional A S T M D297 procedure which requires 32 h, thus being too time-consuming for routine use i n manufacturing. The procedure is at use at G M for troubleshooting and is expected to find a place i n receiving inspection and quality control. Small differences in incoming shipments can be detected, and a correlation between the composition and processing characteristics of the molded parts can be established. This new technique was reported to the Society of Automotive Engineers at their mid-October 1975 meeting i n Detroit.
Thermogravimetric curve for EPDM rubber is shown below. With this type of curve, weight loss steps due to volatilization and/or decomposition of the oil, polymer, and carbon black within the sample can be followed. The derivative curve reveals when one component completes decomposition and another starts
