Headspace vials and caps are used in headspace gas chromatography analysis because of their ability to withstand the pressure from gas. Aijiren headspace vials come in two basic sizes (10 mL headspace vials and 20 mL headspace vials). Both flat bottom and round bottom styles are available for use in a wide variety of headspace instrument platforms.

This type of headspace analysis uses a “purge and trap” method where the sample is placed in a heated vessel and the vessel is purged with a gas. The gas flows from the vessel through a sorbent material which collects the outgassed components. The outgassed components are then flushed from the sorbent material onto the column for GC/MS analysis.

Our gas chromatography (GC) solutions are designed to be customized so that they can fit any laboratory workflow. From Thermo Scientific iConnect injector and detector modules to our performance-leading Thermo Scientific mass spectrometers, we offer the largest portfolio of GC solutions that enable you to innovate and customize your gas chromatography applications.

In the laboratory, a headspace is created by displacing water with high purity helium. The bottle is then shaken upside down for a minimum of five minutes in order to equilibrate the dissolved gases into the headspace. It’s important to note that the bottle must be kept upside down for the remainder of analysis if manually injected.

Headspace GC is a sampling technique that involves the indirect determination of volatile constituents in liquid or solid samples by analysing the vapour phase that is in thermodynamic equilibrium with the sample in a closed system [ 149, 150 ]. It is used predominantly for the determination of volatile constituents present in trace concentrations.

Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer (Figure 1).
