Abstract
The α-amino nitrogen in single amino-acids or in mixtures can be accurately determined by measuring the carbon dioxide released by ninhydrin A simple and convenient unit for the purpose and experimental conditions suitable for a quantitative reaction are described. Recoveries of from 97 to 102 per cent were attained with amounts corresponding to about 0.15 mg of α-amino nitrogen.
