||Gas chromatography (GC)
||Samples that are gaseous at ordinary temperatures and samples that vaporize when heated
·Odorous samples such as petrochemicals, perfumes, and thinner are easier to analyze by GC.
·High molecular weight compounds are measured after pyrolysis.
||Liquid chromatography (LC)
||Liquid samples and solvent-soluble solid samples
·Compared to GC, LC has a wide range of measurement subjects.
·High molecular weight compounds can be analyzed, if soluble in solvent.
