NotesDetailed hydrocarbon analysis (DHA) is a gas chromatographic technique used to determine the composition of spark ignition fuels. Hydrocarbon streams can be characterized by their individual components or by the group type of hydrocarbon (paraffins = P, isoparaffins = I, olefins = O, naphthenes = N, and aromatics = A). This analysis is a blend of all the group types. To help with identification, individual groups were run under the same conditions and can be found in the following chromatograms:
- GC_PC1322 (isoparaffins)
- GC_PC1323 (aromatic compounds)
- GC_PC1324 (olefins)
- GC_PC1325 (naphthenes)
