A multidimensional gas chromatographic system is described for obtaining the content of paraffin, naphthene, and aromatics (PNA) according to both group-type separation and separation by the number of carbons in hydrocarbon mixtures. Several examples of measured PNA results for calibration standards and practical process/product streams are given to illustrate the accuracy, reproducibility, and repeatability of the method. The importance of using purified hydrogen as the carrier gas and a specially prepared molecular sieve 13X wall-coated capillary column for improved P/N separation is stressed.
