Gas Chromatography Vials
There are several options for GC vials. GC vials are available with crimp tops and screw caps. Crimp tops use aluminum crimp seals for a permanent closure. They may be beveled or flat and produce a tighter seal. Snap tops are more convenient because they are easy to open and close, but they still require a blank injection to ensure that there is no carry-over contamination.

GC vials can be used with autosamplers or manual samplers, and Chrom Tech has a wide selection of these glassware items. Crimp style vials, also known as GC vials, are the gold standard in GC analysis. These vials seal well and accommodate volatile compounds. Most gas chromatography vials require an 11mm closure to maintain the sample's integrity. They are available in several colors and septa options, and are compatible with most gas chromatography autosamplers. You can view here for more info.
Shell vials are the most cost-effective solution for HPLC analysis and are supplied with push-in polyethylene caps. Shell vials are available in clear and amber glass and are manufactured from chemically resistant, low extractable borosilicate glass. They also come with write-on patches to minimize identification errors. Screw-neck Amber Glass 2 ml vials are made of pharmaceutical-grade glass and genuine PTFE.
In addition to headspace and plate GC/MS, both techniques detect the major VOCs from P. aeruginosa PAO1. The headspace vials showed a higher signal to noise ratio, while the plate-based method gave lower values. This information can be beneficial for the identification of compounds and species interactions. However, it is important to consider the potential sources of background VOCs when choosing a growth medium for your experiments.
The glass gas chromatography vials are used to formulate a quantitative assay for sesquiterpene synthases. The reaction mixtures are then overlaid with an organic solvent and vortexed to remove hydrocarbon products. The organic phase is then injected into a gas chromatograph-mass spectrometer, where it is analyzed to determine the composition of sesquiterpene products.

In addition to headspace GC, the GC method also uses a closed system to analyze the volatile components. Headspace GC uses a headspace vial to analyze the gas phase in a closed system. The sample is then in equilibrium with the system, allowing for accurate results. The headspace GC vials can be purchased from Aijiren. These gas chromatography vials are made from 33 expansion glass and are marked with three wavy lines
