“…Nitrogen Functions. Maurmeyer (193) recommended that blank values in the modified Van Slyke method for primary amino groups be determined by taking readings before addition of sodium nitrite solution and afterwards for the same length of time as for the actual determination. Narang and Mathur (215) described the use of succinic anhydride as a reagent for the determination of primary and secondary amines and claimed that the reagent was superior to either acetic or phthalic anhydride.…”

The chemical test to determine the amount of amino acids with a primary amino group in the hydrolysates of proteins and food‐stuff, by the treatment of a sample in glycerol with sodium nitrite and acetic acid and a measurement of the volume of nitrogen gas that is generated, this method is generally referred to as the van Slyke determination. This method can be used to determine the amount of amino acids quantitatively, and the result is consistent with the determination using 2,4‐dinitrofluorobenzene (DNFB, the Sanger method) and ninhydrin. However, there are certain amino acids in the protein, which cannot be determined. This method has wide application in amino acid analysis.
