Headspace solid-phase microextraction

Analytical Chemistry, 1993
Headspace solid-phase microextraction is a solvent-free sample preparation technique in which a fused silica fiber coated with polymeric organic liquid is introduced into the headspace above the sample. The volatilized organic analytes are extracted and concentrated in the coating and then transferred to the analytical instrument for desorption and ...

Truffle aroma characterization by headspace solid-phase microextraction

Journal of Chromatography A, 2003
In the present study, a headspace solid-phase microextraction (HS-SPME) combined to gas chromatography-mass spectrometry (GC-MS) has been used to fully characterize aroma of truffles of different species. A fiber of medium polarity (for flavors) was used to avoid discrimination towards very non-polar and polar volatile compounds.

Truffle Aroma Analysis by Headspace Solid Phase Microextraction

Journal of Agricultural and Food Chemistry, 2002
An experimental design has been used to optimize the extraction of volatile compounds from summer truffle aroma (Tuber aestivum) by using headspace solid phase microextraction. The extracted compounds have been analyzed by gas chromatography with a flame ionization detector and by gas chromatography-mass spectrometry (GC-MS).

Headspace solid-phase microextraction for wine volatile analysis

Critical Reviews in Food Science and Nutrition, 2015
The most commonly used technique to prepare samples for the analysis of wine volatile is the headspace solid-phase microextraction (HS-SPME). This method has gained popularity in last few years, as it is a unique solventless preparation technique. In this paper, a summary of recently published studies using HS-SPME for the analysis of wine aromas, with

Critical Comparison of Total Vaporization-Solid Phase Microextraction vs Headspace-Solid Phase Microextraction

2021
Solid Phase Microextraction (SPME) is a popular sampling technique that can be paired with Gas Chromatography/Mass Spectrometry (GC-MS). SPME-GC-MS is used in forensic chemistry due to its simplification of the sample preparation process. Headspace-Solid Phase Microextraction (HS-SPME) is a technique where the sample is heated to generate volatiles in ...

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.
