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.
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.
