Aijiren's Headspace Vials are often used in gas chromatography,a chromatography aeparation and analysis method that USES gas ad a mobile phase. The pattern of vaporization is brought into the chromatography column by the mobile phase. The molecular forca of the fixed phase in the chromatography column is different from that of the sample.

Headspace Gas Chromatography methods have been shown to be effective for the determination of ethanol in low concentrations in fermented beverages (6–8, 20–22). A significant advantage of such methods is the ability to minimize the interference of non-volatile constituents through utilizing the headspace injection ( 6 , 22 , 23 ).
Aijiren has created the title of China’s well-known laboratory consumable supplier with service and product quality. 5000-boxes-of-blue-screw-cap-10-425-hplc-vial-sent-to-singapore Aijiren is a supplier of 2ml hplc vials.
Headspace Analyzer. The increased temperature causes the volatiles to be released from the solution into the “headspace” above the liquid. The headspace is then sampled and analyzed for the presence of the targeted analytes via gas chromatography. g% = g/dl; e.g. 0.08g% = 0.08g of alcohol in 100ml of blood same as 0.08g/dl . ANALYTES DETECTED
For gas chromatography analytical, Headspace vials are widely used for gas chromatography. Laboratory workers have 2 choices of headspace vials. One is crimp and the other one is screw top vial.

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