The members of TARC use a wide variety of chemical techniques to study various problems, both practical and academic. Even though the SLOWPOKE-2 Facility within TARC, which maintained a small, research-grade nuclear reactor for activation analysis studies, has closed, radiochemical research using natural isotopes continues in such areas as pollutant transport in the environment, trace analysis of essential nutrients, and nuclear waste management. The subject of separations interests many TARC members. Thin layer, gas, high pressure liquid, and supercritical fluid chromatographies have been used in studies of ionic and molecular speciation, pollutant and nutrient analyses, and bonded phases. Electrophoretic methods and high pressure liquid chromatography are being applied to biological separations. Atomic spectroscopy has been used for trace analysis and metal speciation. Molecular spectroscopy has been developed for chromatographic detection, identification, and quantification of pollutants. Several TARC members have an interest in mass spectrometry, applying it to both small and large molecule identification and as a separations detector. Electrochemistry has served as a trace analytical technique and is being applied in the study of energy production and storage devices. Chemometrics is being used to enhance and improve chemical measurements through development of new mathematical and chemical data analysis techniques.
