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.

Polypropylene is chemically resistant and the material of choice for pH sensitive samples, sodium or heavy metal analyses.
The PP vials are ideal when working with pH sensitive samples, aqueous samples in pharmaceutical applications, or undertaking sodium analysis.
If you’re analyzing anything that might adsorb into borosilicate glass, or looking to avoid sodium adducts pulled out of glass, these vials seem to do the trick. Using them on triple quad mass spec quite successfully.
