Determination of Trace Volatile N—Nitrosocompounds in White Spirit,Beer and Wine by GC alld Peak Matching Technique

N—Nitrosocompounds are well know carcinogens, we studied and compared four kinds of mass spectrometric methods for the determination of them. The method described here is based on above methods using high resolution peak matching technique which can be used to determine N—Nitrosocompounds in white spirit, beer and wine (50 samples altogether). The results were discussed and estimated.
