Abstract

A method is described for rapid, total nitrogen determinations on samples of biological materials. A modification of the indophenol blue colour reaction is used to determine ammonia released by a semi‐micro Kjeldahl digestion method which uses equipment which is cheap to construct. Using the procedure one worker can analyse 40 samples per hour. Recovery of nitrogen from a standard lysine solution was 98.3 %.
