Clinical and Experimental Hypertension

composition and of ion-exchange resin properties, both very valuable to the amino acid analyst. Detection reagents are evaluated, and gas-chromatographic methods are detailed. There is a good chapter on the important subject of computer application to amino acid analysis. The 46-page chapter on amino acids in physiologic fluids includes methods of a-amino nitrogen and individual methods for phenylalanine, tyrosine, and cystine. The discussion of the application of automated column chromatographic methods to physiologic fluids is detailed, authoritative, and contains normal values and many drawings of chromatographic curves. This book will be of value to persons at every technical level in an amino acid laboratory.
