Gas Chromatography

Gas chromatography is used for the quantitative and qualitative analysis of volatile and semivolatile organics, as well as organic and inorganic gasses. GC/MS is unique in that it offers both identification and quantification of analytes. GC/FID generally offers more sensitivity than the other gas chromatography techniques, but is limited to quantitative analysis. GC/TCD allows us to quantify gasses that are not compatible with GC/FID, such as carbon dioxide, nitrogen, oxygen, etc.

  • Analytes & Methods

    GC/MS
    Identification of trace level volatiles and semi volatiles. Examples would include polycyclic aromatics, PCBs, pesticides, derivatized herbicides, etc.

    Results are both qualitative and quantitative.

    GC/FID
    Gasoline range, diesel range, and residual range organics.

    GC/TCD
    Nitrogen, oxygen, and carbon dioxide in gas samples. Carbon dioxide fraction of natural gas.
