Basic Principles of Headspace Analysis | analytics

Bottom Profile: Headspace vials may be round-bottomed or flat-bottomed. Either type is suitable but round-bottomed vials tend to be stronger and may work more reliably when the autosampler moves the vials into and out of the incubator.

Headspace Vials, 10ml Laboratory Sample Glass Vials -

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. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial .
