Study on GG/FTIR identification of some monoterpenes

Abstract

a-Pinene and its esterified reaction products were identified by capillary GC/FTIR spectroscopy. The GC/FTIR online library searches were performed on an expanded EPA vapor phase library. Comparison identifications by GC/mass spectroscopy were also carried out. The results indicate that GC/FTIR is a powerful tool for monoterpene identification. The conditions for matching the narrow-bore (internal diameter 0.2 mm) capillary column to the Digilab capillary lightpipe are discussed. The sensitivity for several monoterpenes is 10-8 g.
