Determination the content of benzene Series in Air by Gas Chromatography
Date: 2019-08-06
The Benzene is one kind of hydrocarbon, in other way, it is the simplest aromatics. Benzene is a sweet, flammable, carcinogenic, colorless transparent liquid at room temperature, having strong fragrant smell. Methylbenzene and xylene belong to the homologues of benzene and are the cracking products of coal tar fractionation or petroleum. Because of the harmfulness of benzene, benzene compounds have been identified as strong carcinogens by the World Health Organization. As one of the largest chromatography consumables manufacturer in south of China, Aijiren talk about GS analysis in benzene element in air.

The determination of benzene series in air by gas preconcentrator combined with gas chromatography with hydrogen flame ionization detector can replace the method of activated carbon adsorption, carbon disulfide eluting and gas chromatography.  The method is simple and sensitive. In this lab, laboratory consumables can is mainly 10mm crimp headspace vial and chromatographic column. As a chromatography consumables manufacturer, Aijiren supply all kind of chromatography vial, GC vial, HPLC vial, septa, and cap. If you are interested lab, please contact us, Aijiren can supply headspace vial to test.
