Abstract: The present paper reviews various sample preparation methods and quantitative methods for determination of volatile N-nitroso compounds. The methods of sample preparation include distillation, heating digestion and adsorption for separation, and thin layer chromatography, column chromatography and supercritical fluid extraction for purification of volatile N-nitroso compounds. And a simple sample preparation method, namely solid micro-extraction, is also reviewed. Quantitative and qualitative methods including spectrophotometry, thin layer chromatography, gas chromatography, liquid chromatography and micellar electrokinetc capillary chromatography are introduced.

Key words: N-nitroso compound, N-nitrosamine, analysis method
