Selected analytes Selected analytes sometimes have to be analyzed at parts per million levels. Typical examples are aromatic amines, nitrosamines, reactive intermediates left from the synthesis, or certain solvent residues, i.e., all components that are known to be noxious and thus must be controlled separately. 

A solution of 0.1 g of substance in 4 ml of 2 n HCl is cooled to 5 and mixed with a 10% NaN02 solution, until a drop of the mixture gives a blue color with Kl-starch paper. Nitrogen is set free by amides, aliphatic primary amines, and amino acids (amides are converted to acids, and amines to alcohols yields are often small, but the products can be isolated). A yellow oil or a solid substance (nitrosamine) is formed in the case of secondary aliphatic and aromatic amines. Nitrosamines can be extracted with ether.
