[Analysis of volatile N-nitrosamines. A brief review].

The different steps of analysis of volatile N-Nitrosamines: separation from product, clean up, detection, quantification and confirmation are reviewed and discussed. The two best analysis procedures are: 1) combined gas-chromatography; mass-spectrometry, 2) combined gas-chromatography; thermal energy analyzer. However a bundle of proofs is always necessary to ascertain the presence of Nitrosamines.
