E-Book Overview
College-level students of chromatography will find the 2-volume reference Encyclopedia Of Chromatography an invaluable reference offering more than just definitions of physics processes and chemistry systems. Topics range widely from the identification of additives in biopolymers and capillary electrophoresis to displacement equilibrium, known in chromatography for its usefulness in analytical scale separations. It's the depth and detail of these articles, arranged as an A-Z encyclopedic reference and authored by major contributors from around the world, which makes the set both authoritative and exhaustive. Add charts, graphs, tables of results and rates, and formulas and you have a far-reaching reference. Specialty collections with solid science holdings will consider this newly updated and expanded second edition of the Encyclopedia Of Chromatography to be a 'must'.

b -Agonist Residues in Food, Analysis by LC Nikolaos A. Botsoglou Aristotle University, Thessaloniki, Greece INTRODUCTION b-Agonists are synthetically produced compounds that, in addition to their regular therapeutic role in veterinary medicine as bronchodilatory and tocolytic agents, can promote live weight gain in food-producing animals. They are also referred to as repartitioning agents because their effect on carcass composition is to increase the deposition of protein while reducing fat accumulation. For use in lean-meat production, doses of 5 to 15 times greater than the recommended therapeutic dose would be required, together with a more prolonged period of in-feed administration, which is often quite near to slaughter to obviate the elimination problem. Such use would result in significant residue levels in edible tissues of treated animals, which might in turn exert adverse effects in the cardiovascular and central nervous systems of the consumers.[1] There are a number of wel
