Determination of methanol in biodiesel by headspace solid phase microextraction

Bioresource Technology, 2008
A new direct gas chromatography procedure (headspace solid phase microextraction) was developed for the quantitative determination of methanol in biodiesel. The analysis was performed by exposing a carboxen-polydimethylsiloxane SPME fiber assembly to the headspace of the biodiesel sample.

Static headspace, solid-phase microextraction and headspace solid-phase microextraction for BTEX determination in aqueous samples by gas chromatography

Analytica Chimica Acta, 2000
Abstract The determination of benzene, toluene, ethylbenzene and xylenes (BTEX) in aqueous samples by gas chromatography with flame ionization detection (GC–FID) with three sampling techniques, viz. static headspace (HS), solid-phase microextraction (SPME) and combined HS–SPME by using a polydimethylsiloxane fiber has been investigated.

Optimisation of headspace solid-phase microextraction for the analysis of volatile phenols in wine

Journal of Chromatography A, 2003
Headspace solid-phase microextraction has been applied to the analysis of volatile phenols in wine. Silica fibre coated with Carbowax-divinylbenzene was found to be more efficient at extracting these compounds than other fibres such as those coated with polydimethylsiloxane, polyacrylate, carboxen-polydimethylsiloxane, and polydimethylsiloxane ...
