✦ Synopsis

Primary and secondary amines can be directly separated as 4'-nitroazobenzene-+carboxamides by gas-liquid chromatography.

Using silicone grease as a liquid phase and a constant temperature of z70°, the separation was performed with derivatives of primary and secondary aliphatic, alicyclic, and aromatic amines up to Cl2 and several tobacco alkaloids. A preparation technique is described whereby pure comptiunds are obtained from complex mixtures ready for mass spectrometric identification.

A short review is given with respect to the examination of tobacco and tobacco smoke.
