Abstract
A method using O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochlor ide (PFBHA) coated C-18-silica gel cartridges was applied in the ident ification of biogenic carbonyls in air as their oxime derivatives. The PFBHA-derivatives of the terpene oxidation products pinonaldehyde, no pinone, 3-(1-methylethenyl)-6-oxo-heptanal and AMCH were separated and identified by means of gas chromatography/mass spectrometry with elec tron impact and chemical ionisation. Sampling of 50 L air through the PFBHA coated cartridges results in a detection limit of 2 ppbv for the carbonyls with this method.
