6ml 20mm Crimp Top Headspace Vials for Supplier
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 headspace instrument platforms.
Working Principle of Headspace Vial
Headspace analysis permits the detection of volatile substances in a liquid or solid sample and minimizes column contamination. A small volume of the sample is placed in a vial sealed with a septum and the sample vial is equilibrated at an appropriate elevated temperature.
A headspace sample is usually prepared in a vial containing the sample, the dilution solvent, a matrix modifier and the headspace. Volatile components from complex sample mixtures can be extracted from non-volatile sample components and isolated in the headspace or gas portion of a sample vial. A sample of the gas in the headspace is injected into a GC system for the separation of all of the volatile components.
