Abstract

Discuses the criteria of purity of substances and the physical techniques that are used in achieving purity. Such techniques as extraction, distillation, crystallisation, sublimation, chromatography in its various applications, electrophoresis, drying, vacuum line procedures, solvents, as well as taking advantage of a knowledge of the dissociation properties of ionisable substances are described in great detail. Instrumentation for checking purity is only briefly mentioned as extensive information about these already exists in the literature. Recent advances in physical methods are also discussed. A large number of useful tables (34 tables) are provided which should be helpful ...
