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.
Thermo Scientific headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.
