Apr 05, 2019 · In GC, the column is often made of fused silica (glass beads), with a polymer coating. The sample is vaporized, either through heating in the sample vial, where a needle draws an aliquot of the headspace (region of a vial above the liquid) containing gases, or a liquid solution can be injected into the instrument for subsequent heating.

To run the sample on the GC, first fill a vial with a wash solvent, such as acetonitrile or methanol. Prepare the sample, being certain to use glass syringes and glass vials as plastic residues can contaminate the GC. Now add the prepared sample to a vial with a pipette. Fill at least half way, so that the autosampler syringe will be fully
