Field method for the determination of aromatic primary amines in air. Part II. Development of a sensitive field test

Abstract

A simple field test for primary aromatic amines in air is described in which the sample is drawn through an impregnated paper to form a coloured stain produced by the reaction of aromatic primary amine groups with 4-(dimethylamino)cinnamaldehyde. The test is sensitive to about 10 ng of amine and has been found to be applicable to eleven different amines. It does not distinguish individual compounds and can be affected by airborne alkaline or acidic compounds.
