Abstract:

This invention concerns analysis by high performance liquid chromatography HPLC of crude oils and petroleum products. In one embodiment of the invention a sample is quantitatively separated into saturates, alkyl benzenes and polynuclear aromatics using a system comprising a column packed with a porous silica packing material having a polar amino-cyano bonded phase in tandem with a column packed with a tetranitorfluorenimino packing material, and a dielectric constant detector. In another embodiment of the invention a sample is qualitatively separated into saturates, olefins, and total aromatics using a system employing an olefin-selective column and a dielectric constant detector.
