Abstract: For analysis of composition of perfumery product,two detection technologies,one-dimensional gas chromatography+time-of-flight mass spectrometry (1DGC TOF-MS) and comprehensive two-dimensional gas chromatography+time-of-flight mass spectrometry (GC×GC TOF-MS) were applied.Conventional components in perfumery product were identified and classified.Results showed that 1DGC TOF-MS can identify 172 compounds with high matched results with MF>750 when matched with dedicated standard library.Among these compounds,they are constituted of 34 terpenes,25 alcohols,37 esters,15 ethers,23 ketones,12 aldehydes,26 acids and other heterocyclic compounds.While by the help of automatic processing of software and manually deduct background,GC×GC TOF-MS can identify 722 compounds with matched results MF>750,and those compounds are classified 125 terpenes,168 alcohols,79 esters,92 ketones,33 aldehydes,225 heterocyclic and alkane compounds.

Key words: perfumery, comprehensive two-dimensional gas chromatography, time-of-flight mass spectrometry
