Structure of the Second Edition

The structure of the second edition follows that of the first edition, with novel applications contained in sections attached to the individual chapters. The present chapter covers mass spectroscopy, with additional applications being found in the individual chapters, as well as advances in common detectors, unusual modes of chromatography, and general theoretical advances. 

This third edition essentially retains the structure of the second edition but its contents have been revised, with considerable changes in some parts. Thus, account is taken of the fact that a new generation of antidepressants has been available for some years, that concepts of the mechanisms of neuroleptic action have altered several times and have led to products with new mechanisms of action, and that therapeutic advances have even been recorded in a field that was only recently considered to be hopeless, namely Alzheimer s disease. New methodological developments, especially in the use of imaging techniques in psychiatry, and changes in opinions on the best possible use of psychopharmaceuticals and their duration of use in schizophrenia and depression have been suitably taken into account.
