Headspace Solid-Phase Microextraction Analysis of Methyl Isothiocyanate in Wine

Journal of Agricultural and Food Chemistry, 1997
Methyl isothiocyanate (MITC) is used as soil fumigant for several vegetable diseases and as antifermentative agent in wine. A new headspace solid phase microextraction (HS-SPME) method for analysis of MITC in wine is here described. This method is fast, inexpensive and does not require any solvent.

Sensitive quantification of sulfur compounds in wine by headspace solid-phase microextraction technique

Journal of Chromatography A, 2005
A sensitive solid-phase microextraction and gas chromatography-pulsed flame photometric detection technique was developed to quantify volatile sulfur compounds in wine. Eleven sulfur compounds, including hydrogen sulfide, methanethiol, ethanethiol, dimethyl sulfide, diethyl sulfide, methyl thioacetate, dimethyl disulfide, ethyl thioacetate, diethyl ...

Development of a Novel Ultrasound Vacuum-Assisted Headspace Solid-Phase Microextraction Approach for Determination of Solvent Residuals in Pharmaceuticals and Comparison with Traditional Headspace Solid-Phase Microextraction Method

Journal of Chromatographic Science
Abstract In this report, an ultrasonication and vacuum-assisted headspace solid-phase microextraction procedure followed by gas chromatography-flame ionization detection (UVA-HS-SPME-GC-FID) was proposed for direct extraction of solvent residuals, including benzene, toluene, ethyl benzene, m,p-xylene and o-xylene, in pharmaceutical ...

Vacuum-assisted headspace solid-phase microextraction in food analysis: basics and applications

Analytica Chimica Acta
Vacuum-assisted headspace solid-phase microextraction (Vac-HSSPME) is increasingly recognized as a powerful and environmentally friendly technique for extracting volatile and semi-volatile compounds from complex food matrices. While conventional HSSPME has been widely applied, its limitations in extracting low-volatility and matrix-bound compounds have
