Crimp Cap HS Vial: PN#21162 and Crimp Cap: PN#21761. Sample preparation included adding propane, butane, and isobutane standards in N,N-Dimethylacetamide (DMA) along with α,α,α-Trifluorotoluene as the ISTD to a 20 mL HS vial. To model the vial cap’s ability to keep these volatile compounds from escaping the vial, we designed a time study.

The Headspace Sampling Process. Sample is transferred to a vial suitable for headspace analysis and immediately capped to minimize loss of volatile components. Once the headspace vial is capped, these low-boiling compounds begin to migrate between the sample and the headspace layer, ultimately reaching equilibrium (Figure 2).
