Optimization of Headspace Solid Phase Microextraction Procedure for Trace Analysis of Toluene

International Journal of Occupational Safety and Ergonomics, 2008
This study describes optimization of headspace solid phase microextraction followed by gas chromatography equipped with a flame ionization detector for toluene at trace level in spiked urine. The parameters affecting the extraction and gas chromatographic determination of analytes were studied: extraction time and temperature; desorption time and ...

Downsizing vacuum-assisted headspace solid phase microextraction

Journal of Chromatography A, 2013
Recently, we proposed a new headspace solid-phase microextraction (HSSPME) procedure, termed vacuum-assisted HSSPME (Vac-HSSPME), where headspace sampling of 10mL aqueous sample volumes took place in 500 or 1000mL sample containers under vacuum conditions.

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 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).

Solid-Phase Microextraction and Headspace Solid-Phase Microextraction for the Determination of Polychlorinated Biphenyls in Water Samples

Analytical Chemistry, 1998
A solid-phase microextraction (SPME) method has been developed for the quantification of polychlorinated biphenyls (PCBs) in water samples. Parameters such as sampling time, volume of water, volume of headspace, temperature, addition of salts, and agitation of the sample were studied.

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.

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 ...
