A nitrosamide-specific detector for use with high-pressure liquid chromatography.

A highly specific automated method for identification of nitrosamides has been developed for use in conjuction with reversed-phase high-pressure liquid chromatography. The method is based on the well-known Griess reagent, and is capable of sensitivities of 0.5 nmoles of injected nitrosamide in most cases. The method may be used for analysis of nitrite, nitrosamides, nitrosocarbamates, and alkylnitrites.
