Many of the aroma compounds are volatile thus suited for Headspace Gas Chromatography/Mass Spectrometry (HS-GC/MS) analysis. HS sampling heats up the sample and transfers the volatiles to the GC/MS without the need for steam distillation, or solid2.

Headspace analysis of VOCs in urine samples using solid phase micro extraction (SPME) coupled to gas chromatography - mass spectrometry (GC-MS) is one of the most used techniques. However, it generally produces a limited profile of VOCs if applied to fresh urine.

Headspace analysis was carried out on a Gerstel MPS2 sampler and gas chromatograph/5973 mass-selective detector (Aijiren Technologies, Stockport, UK). Sample point National Grid Reference

Headspace gas chromatography (HSGC) is one of the most elegant methods of gas chromatographic analysis. This chapter describes possible applications of HSGC-methods in the field of residue analysis in foods and packaging materials, and clarifies this by means of selected examples. Static HSGC makes use of the thermodynamic equilibrium between

Gas Chromatography. Headspace analysis is not limited to the identification of unknowns. It is integral to various chemical studies including the fate and behaviour of molecules. This technique can be used within these studies to document the effects of samples on the outside environment, and vice versa. This method is used extensively within

Headspace gas chromatography/ mass spectroscopy is the analysis of the volatile and semi-volatile organic compounds given off by a sample during heating or over time. 0.1-10 grams is the typical sample size, and virtually any sample that’s not highly volatile can

These include proton transfer reaction-mass spectrometry (PTR-MS), gas chromatography–mass spectrometry and headspace solid-phase microextraction (HS-SPME) [12,13,14]. The first used a fingerprinting approach for discerning palm oil by geographical origin, the second intended to identify specific VOCs which contributed to palm oil flavour, whilst the latter was optimised to detect furfural

Headspace gas chromatography is a group of analytical techniques that combine extraction of the analyte of interest from a condensed phase sample into a gas phase and its subsequent analysis by gas chromatography [1–3]. In general, headspace

Gas chromatography–olfactometry (GC–O) is a powerful tool for the study of chemical compounds responsible for wine aroma. However, what is quantified by the GC–O process is quite distinct, from both qualitative and quantitative points of view, from the perception experienced during actual wine consumption.
