Headspace vials are a kind of laboratory vials for headspace 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 evaporate them at the top. 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.
