Detailed Hydrocarbon Analysis (DHA) Using Gas Chromatography (GC)

By: Michael D. Buchanan, Reporter US Volume 28.4

Detailed hydrocarbon analysis (DHA) of petroleum samples is commonly performed by gas chromatography (GC) using a Petrocol™ capillary GC column. This family of columns is characterized by high efficiency and great reproducibility. The chromatogram shown in Figure 1 was obtained by analyzing a petroleum reformate on a 100 m Petrocol DH column.
