Aug 15, 2020 · In gas chromatography, the components of a sample are dissolved in a solvent and vaporized in order to separate the analytes by distributing the sample between two phases: a stationary phase and a mobile phase. The mobile phase is a chemically inert gas that serves to carry the molecules of the analyte through the heated column.

Headspace Glass Vials & Headspace Caps. Aijiren headspace vials come in two basic sizes (10 mL glass vials and 20 mL glass vials; Crimp caps are most common however many customers use screw sample and application dependent; clear glass vials and amber vials are available; 11 mm caps, 18 mm caps, and 20 mm caps are engineered to prevent sample contamination while providing consistent, secure seals.
