Odor-contributing volatile compounds of a new Brazilian tabasco pepper cultivar analyzed by HS-SPME-GC-MS and HS-SPME-GC-O/FID [PDF]
Abstract The cultivar BRS Avai was originated from recurrent phenotypic selection in the original American cultivar Tabasco Macllhenny™, used in the worldly famous Tabasco pepper (Capsicum frutescens L.) sauce. The determination of the aroma profile of this new cultivar could reveal important qualitative descriptors that will help in future crosses and

STUDY OF RUGGEDNESS HS-SPME PROCEDURE FOR ORGANOTIN ANALYSIS BY GC-PFPD [PDF]
In this work, the ruggedness of several variables suspected influents on extraction of ethylated organotins (butyl-and phenyltins) by Solid Phase Microextraction in headspace mode (HS-SPME) was realized by using Gas Chromatography-Pulsed Flame Photometric detection (GC-PFPD).

Searching for Potential Markers of Glomerulopathy in Urine by HS-SPME-GC×GC TOFMS [PDF]
Volatile organic compounds (VOCs) exiting in urine are potential biomarkers of chronic kidney diseases. Headspace solid phase microextraction (HS-SPME) was applied for extraction VOCs over the urine samples. Volatile metabolites were separated and identified by means of two-dimensional gas chromatography and time of flight mass spectrometry (GC × GC ...

Authentification of fruit spirits using HS-SPME/GC-FID and OPLS methods [PDF]
AbstractThis research provides an accurate description of the origin for fruit spirits. In total, 63 samples of various kinds of fruit spirits (especially from apples, pears, plums, apricots and mirabelle) were analysed using headspace-solid phase microextraction and gas chromatography with flame-ionization detector.
