Description
Analysis Note
Detailed hydrocarbon analysis (DHA) is performed on long non-polar columns. Elution occurs in order of lowest boiling point to highest. The chromatogram shown here is of a gasoline sample using a 100 m Petrocol DH column. The long column length and 60 ºC isothermal oven temperature allow the separation of many components in this complex sample. Compounds identified range from propane (peak 1) to 1-methylnaphthalene (peak 96). Retention index libraries exist for this column, adding to its usefulness.
