Economical headspace vials and caps for gas chromatography

Vials vs. 96-Well Plates for Chromatography

11/8/2020 · Vials are the most reliable option for gas chromatography methods. Gas chromatography requires a tight seal to avoid evaporation. Closures such as crimp caps tightly seal vials shut, making them the best option for gas chromatography. Vials are also a 96-Well

Crimping – Is My Headspace Vial Tight Enough? | CRS

2/10/2015 · Genesis Packaging Technologies, for example, manufactures a Residual Force Tester that is used to measure the sealing force in pharmaceutical vials sealed with stoppers and aluminum caps. In analytical labs by comparison the most common test is a “twist-test”, in which the chemist attempts to twist the cap to determine if it is tight enough from their own experience.

Headspace Vials, 10ml Laboratory Sample Glass Vials -

Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top.
