Abstract	SARA (saturates, aromatics, resins, and asphaltenes) separation and quantification are used to characterize the composition of crude oil and bitumen. Saturate hydrocarbons are the most valuable fraction of the oil industry. They contain vital geochemical information for determining the origin and formation of petroleum fluids and for assessing the hydrocarbon potential and sedimentary environment of source rocks. Consequently, it is necessary to further separate the saturate fraction into normal paraffins, iso-paraffins and naphthenes (PIN fractions). Unfortunately, the conventional approach to PIN separation has yet to be reported in the literature. Authors present an efficient method enabling further separation of the saturate fraction of crude oil or bitumen into PIN fractions through the automated multi-dimensional high performance liquid chromatography system (AMD-HPLC).
