Headspace solid-phase microextraction analysis of volatile components of spices

Chromatographia, 2002
Headspace solid-phase microextraction (HSSPME) coupled with gas chromatography-mass spectrometry (GC-MS) has been used to isolate volatile compounds from three different spices (basil, oregano, and bay leaves). SPME conditions were optimized before the experimental extractions, to achieve optimum recovery of the volatile compounds.

Solid-Phase Microextraction Method Development for Headspace Analysis of Volatile Flavor Compounds

Journal of Agricultural and Food Chemistry, 2000
Solid-phase microextraction (SPME) fibers were evaluated for their ability to adsorb volatile flavor compounds under various conditions with coffee and aqueous flavored solutions. Experiments comparing different fibers showed that poly(dimethylsiloxane)/divinylbenzene had the highest overall sensitivity.

Headspace solid‐phase microextraction for direct determination of volatile phenols in cider

Journal of Separation Science, 2009
AbstractA headspace solid‐phase microextraction coupled to gas chromatography‐tandem mass spectrometry (GC‐MS/MS) method was optimised and validated for the determination of 4‐ethylguaiacol, 4‐ethylphenol, 4‐vinylguaiacol and 4‐vinylphenol, involved in the presence of Brett character, in ciders.

Determination of nerolidol in teas using headspace solid phase microextraction–gas chromatography

Food Chemistry, 2014
Nerolidol is an important volatile compound found in tea aroma, consumption of which has been associated with good health. A novel approach for the quantitative determination of nerolidol in teas has been developed using a headspace solid phase microextraction (HS-SPME) and a gas chromatography-flame ionization detector (GC-FID).

Headspace solid-phase microextraction analysis of 3-alkyl-2-methoxypyrazines in wines

Journal of Chromatography A, 2002
A procedure to determine 3-alkyl-2-methoxypyrazines in wines is described. It is based on the headspace solid-phase microextraction (HS-SPME) technique after a clean-up of the sample by distillation (previously acidified to pH 0.5) to remove ethanol and other volatile compounds that can interfere in the SPME.

Multiple headspace-solid-phase microextraction: An application to quantification of mushroom volatiles

Analytica Chimica Acta, 2013
Multiple headspace-solid phase microextraction (MHS-SPME) followed by gas chromatography/mass spectrometry (GC-MS) and flame ionization detection (GC-FID) was applied to the identification and quantification of volatiles released by the mushroom Agaricus bisporus, also known as champignon.

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.

Optimization of Headspace Solid-Phase Microextraction for Analysis of Wine Aroma Compounds

American Journal of Enology and Viticulture, 2000
Headspace solid-phase microextraction (SPME) is a fast and simple sampling method for analysis of volatile compounds, but quantitation can be affected by sample matrix and sampling conditions. Sampling time and temperature are particularly important in controlling analyte response, and the effects vary for different compound classes and volatilities ...
