Sampling and determination of formaldehyde using solid-phase microextraction with on-fiber derivatization
Gaseous formaldehyde is sampled by derivatization with o-(2,3,4,5,6- pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) adsorbed onto poly (dimethylsiloxane)/divinylbenzene solid-phase microextraction fibers. The product of the reaction is an oxime whi
Detection Limits of Electron and Electron Capture Negative Ionization-Mass Spectrometry for Aldehydes Derivatized with o-(2,3,4,5,6-Pentafluorobenzyl)-Hydroxylamine Hydrochloride
In contrast to common expectations, the differences in limits of detection (LODs) between electron capture negative ionization (ECNI) and electron ionization (EI) mass spectrometry (MS) were found to be insignificant for a wide range of aldehydes derivati

Henry's law constants of carbonyl-pentafluorobenzyl hydroxylamine (PFBHA) derivatives in aqueous solution
In situ derivatization of airborne carbonyls can increase the efficiency of sampling methods aimed at the quantification of these trace components in urban and rural and rural atmospheres. The design of efficient samplers based on aqueous solutions of the

Identifying airborne carbonyl compounds in isoprene atmospheric photooxidation products by their PFBHA oximes using gas chromatography/ion trap mass spectrometry
Coupled with gas chromatographic/mass spectrometric detection, the oxime formation of aldehydes and ketones by reaction with O-(2,3,4,5,6-pentafluoro- benzyl)hydroxylamine hydrochloride (PFBHA) can be used to determine multi- functional airborne carbonyls
