Sample Vials : Waters
LC/GC Certified vials are tested by LC/UV for residues of chemicals used in processing and packaging vials. The septa are tested by headspace GC to ensure low levels of low molecular weight polymer. These vials are suited for analyte concentration in the µg/mL concentration; typically detectors like UV and RI.

Sample Preparation Techniques for Gas Chromatography | IntechOpen
Jul 30, 2018 · In gas chromatography (GC), the sample is vaporized and injected onto the head of a chromatographic column. Elution is brought about by the flow of an inert gaseous mobile phase such as helium, argon, nitrogen, carbon dioxide, and hydrogen. In GC, the mobile phase does not interact with molecules of the analyte, and it only transports the analyte through the column. In two general kinds of GC
