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 GC injection technique is used to analyze low to trace levels of volatile components in liquids and solids. Liquid Samples. In general if the sample is a viscous liquid it is a good candidate for injection with the headspace technique. Examples of this type of sample are cosmetic cream and lotions, elixirs, and used motor oil.
