This volume presents a group of selected papers given at the November, 1972, meeting of the Eastern Analytical Symposium. As has always been the intent of the series, "Progress in Analytical Chemistry," the papers are written by authorities who are also active workers in their fields. Included are applications of Raman Spectroscopy, X-Ray Diffraction, Emission Spectroscopy, Nu- clear Magnetic Resonance, Liquid Chromatography, Thin-Layer Chromatography, Pyrolysis Gas Chromatography, Mass Spectrometry, Gas Chromatography and the powerful marriage of the last two. In modern analysis there is a...

With the rise in general awareness of the effects of trace chemicals in the environment on man's health, it has been realized that traditional methods of analysis are often inadequate. Reliable analyses are needed in the fractional parts-per- million range of contaminants in condensed phases, and of the order of micrograms per cubic meter in air. Trying to get meaningful answers regarding such minute amounts raises cogent problems in all stages of an analysis. It is most appropriate, therefore, that the 1971 Eastern Analytical Symposium should have four half-day sessions devoted to this...

The analytical chemist is in the forefront of the race to use computers in laboratory work. The modern laboratory has a large number of instruments churning out information, and mechanized procedures for handling the huge amount of data are imperative. The marriage of instruments and computers is offered as a way of easing the burden on the scientist, as well as optimiz- ing the performance of the analytical instruments. Computer systems can be applied to all the major analytical instrument procedures, and many of the leading instrument manufacturers are developing and producing systems for...

Volume 8 in the series Progress in AnaZyticaZ Chemistry presents a selection of the papers given at the 1975 Eastern Analytical Symposium. The analytical chemist is under constant pressure not only from the research chemist whose sampIes he must characterize and control, but also from an ever-increasing group of governmental agencies stimulated by public concern over health and environmental problems, to determine the most sophisticated kinds of compounds as lower and lower levels. The subjects covered in these papers are wide-ranging, from the analysis of incinerator effluents to the...

The Fifteenth Eastern Analytical Symposium and the Twelfth National Meeting of the Society for Applied Spec- troscopy were held jointly in New York, November 14-16, 1973. In cooperation with the Detroit Analytical Chemists' Association, the Anachem Award in Analytical Chemistry was presented at this meeting to Dr. Rosalyn S. Ya1ow, the co- inventor (with Dr. S. Berson) of the radioimmunoassay technique. It is our privilege to include in this volume Dr. Ya1ow's award address, a review of radioimmunoassay, together with a series of three papers on related subjects, respectively by Dr. Juan M....
