ISO 22303:2008 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.
Abstract
Overview
ISO 22303:2008 specifies a laboratory method for the determination of tobacco specific nitrosamines () - 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 standard defines a procedure followed by organic elution, concentration and quantification by . It is published by ISO as ISO 22303:2008.
