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).

What types of samples are typically analyzed using headspace with gas chromatography? 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

Headspace-gas chromatography (HS-GC) analysis can be applied successfully for the analysis of VSCs in different liquid matrices. It can be also applied in physical chemistry studies of these compounds, being a valuable tool for acquiring data on gas–solid and gas–liquid systems.

As such, headspace gas chromatography offers a method for determining if there is natural biodegradation processes occurring in contaminated aquifers. [5] For example, fuel hydrocarbons will break down into methane. Chlorinated solvents such as trichloroethylene, break down into ethene and chloride.

Feb 29, 2016 · The headspace gas can be sampled manually using a heated gas tight syringe (to avoid condensation) or by using an automated system employing a heated gas loop which transfers the sample to the GC column via a heated transfer line. In each case a split/splitless injector is used to facilitate gas sample introduction. References

I want to share some of the most common issues that we see with peak shapes in Gas Chromatography in the hope that if you spot some of these in your own work, you may be able to intercept problems and deal with them more effectively. Example 1 – Peak Tailing. Figure 1: Chromatograms showing worsening peak tailing effects.

Aug 28, 2022 · The carrier gas system consists of carrier gas sources, purification, and gas flow control. The carrier gas must be chemically inert. Commonly used gases include nitrogen, helium, argon, and carbon dioxide. The choice of carrier gas often depends upon the type of detector used.

Our portfolio includes clear glass vials for your general use and amber vial for applications involving light sensitive sample analytes. Our complete range of glass chromatography vials are made from Type 1 borosilicate glass which is compatibility with the widest range of sample matrices including acidic, neutral or alkaline pHs.

Headspace Analysis works on the principle of Tunable diode laser absorption spectroscopy (TDLAS), a non-destructive method able to measure the concentration of a certain gas in closed container even at very low detection limits, with a sufficient headspace size to pass through with a laser beam.
