Tobacco. Determination of tobacco specific nitrosamines. Method using alkaline dichloromethane extraction Ingestion-build-50790 cross for pipe couplings1 Scope This Technical Specification specifies the procedure for the determination of the tobacco specific nitrosamines (TSNAs): N nitrosonornicotine (NNN), N nitrosoanatabine (NAT), N nitrosoanabasine (NAB) and 4 (methylnitrosamino) 1 (3 pyridyl) 1 butanone (NNK) in ground leaf tobacco, manufactured tobacco and tobacco products. The determination is by means of gas chromatography.
