Basic principles of headspace analysis. A headspace sample is usually prepared in a vial containing the sample, the dilution solvent, a matrix modifier and the headspace. Volatile components from complex sample mixtures can be extracted from non-volatile sample components and isolated in the headspace or gas portion of a sample vial.

Dec 17, 2019 · Dec. 17th, 2019. Headspace sample handling is a convenient and fast sample pretreatment method in gas chromatography. The principle is to place the sample to be tested in a closed container, by heating up the volatile components from the sample base to spread out, in the gas liquid (or gas solid) in both phases to achieve balance. Then direct

Headspace gas chromatography is most suited to the analysis of the very light volatiles in samples that can be efficiently partitioned into the headspace gas volume from the liquid or solid matrix sample. Higher boiling volatiles and semi-volatiles are not detectable with this technique due to their low partition in the gas headspace volume.

These headspace vials are made of superior quality 1st hydrolytic class glass (Type 1) and have a thicker glass wall to withstand higher temperatures and internal pressures for the analysis of volatile gas in the vial’s headspace.

In this study, the volatile compounds of porcupine liver were analyzed by headspace solid phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). Results showed that

Jun 30, 2021 · In recent years, headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) has been applied in the detection of trace volatile components based on the combined advantages of fine separation efficiency from GC and high sensitivity of IMS (Hernández-Mesa et al., 2019).

The essence of this experiment is that the volatile sample is heated and vaporized to form a gas in the top space of the headspace vial and then diffuses. Finally, the gas in the vial enters the gas phase detection. Top space gas analysis with the help of a headspace vial helps automate quality control or sample selection. Using modern
