Solid-phase microextraction–gas chromatography–direct deposition infrared spectrometry as a convenient method for the determination of volatile compounds from living organisms

Solid phase microextraction coupled to liquid chromatography. Analysis of organosulphur compounds avoiding artifacts formation

“…Since these compounds are responsible of different biological activities and contribute to sensory attributes of the garlic products, the precise determination of the OSCs profiles is of interest. It is important to take into account that TS, including allicin, can also suffer transformations during the different stages of the analytical process (isolation, gas-chromatographic analysis and mass identification -when hot ionisation source are used-or combination of them) due to the reactive characteristics (Auger, Rousset, Thibout, & Jaillais, 1989;Block, 1993). This fact leads to artifacts formation, reporting thus, OSCs profiles no representative of the original sample (Block, 1993(Block, , 2013, however there are more recently publications about OSCs analysis employing GC-MS.…”

Identification of pheromones in mouse urine by head-space solid phase microextraction followed by gas chromatography–mass spectrometry

“…To date, four main detection systems coupled to gas chromatography (GC) have been used to accurately determine pheromones: mass spectrometry (MS) [10], Fourier transform infrared spectroscopy (FTIR) [11], flame ionisation detection (FID) [12] and electroantennographic detection (EAD) [13].…”

Sexual attraction and male pheromone evidence in the asparagus fly, Platyparea poeciloptera

“…Their role in sexual behaviour has previously been suspected (Seguy, 1951). After the identification of a component emitted by the male (Auger et al, 1998), the emission of a sex pheromone in this fly is being studied by olfactometric methods in order to explore potential biological control processes.…”
