Semi volatile compounds

Recommended chromatographic column for volatile compounds

1、 HP-5ms column, used for EPA methods 8270 and 525;

2、 DB-XLB column, used for polychlorinated biphenyls homologues;

3、 HP-5ms or DB-35ms columns for polycyclic aromatic hydrocarbons;

4、 DB-5ms or DB-XLB column, used for phenolic compounds

Semi volatile compounds are typically extracted from solid samples or other environmental matrices, using GC chromatography columns with more precise retention time repeatability and high-performance mass spectrometers, mainly for situations that require frequent analysis.
