ABSTRACT:
A method of analysis by high performance liquid chromatography is provided for obtaining an analysis of three components, namely acyclic paraffins, cycloparaffins and unsaturates, present in a liquid hydrocarbon mixture. The method comprises introducing a sample of the mixture to be analyzed into an unsaturates-selective column, passing the eluents from the unsaturates-selective column to a second column, eluting the separated components from the second column, detecting the presence of paraffins and naphthenes in the effluent from the second column, eluting the separated components from the unsaturates-selective column, and detecting the presence of unsaturates in the effluent from the unsaturates-selective column. The unsaturates-selective column is a silver-modified ion exchange column. The second column is a slurry packed column packed with a microparticulate material. The detector is a dielectric constant detector.
