Headspace vials and caps are used in headspace gas chromatography analysis because of their ability to withstand the pressure from the gas. Aijiren headspace vials come in three basic sizes (6ml headspace vials, 10mL headspace vials and 20mL headspace vials). Both flat bottom and round bottom styles are available for use in a wide variety of []

Aug 28, 2022 · Gas chromatography (GC) is a very commonly used chromatography in analytic chemistry for separating and analyzing compounds that are gaseous or can be vaporized without decomposition. Because of its simplicity, sensitivity, and effectiveness in separating components of mixtures, gas chromatography is an important tools in chemistry.

Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

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 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.

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).

Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can accommodate virtually any matrix. How does headspace sampling work?

TurboMatrix HS 40 The core of PerkinElmer’s headspace is our patented pressure-balance technology that far surpasses valve and loop in performance when it comes to accuracy and repeatability. Pressure-balance provides rapid transfer of analytes to the GC without re-equilibration in a gas-sampling valve or syringe and minimizes loss of analytes.

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.
