A B S T R A C T CHROMATOGRAPHIC ANALYZER Method and apparatus for analyzing a hydrocarbon sample are provided. The apparatus employs a highly polar column to separate the aromatics from non-aromatic components. The non-aromatic effluent from the highly polar column is passed to a 13X MSCOT (molecular sieve coated open tubular) column and a first less polar column. In a second configuration the highly polar column is backflushed into a second less polar column. The 13X MSCOT (molecular sieve coated open tubular) column separates isoparaffins and any coeluting olefins, normal paraffins and naphthenes by carbon number while the first less polar column individually separates the paraffins, naphthenes and olefins. Thus, the individual olefins may be removed from the data of the 13X molecular sieve column. The second less polar column is employed to separate individual aromatics. The method for analyzing a hydrocarbon sample separates the aromatics of the sample from the isoparaffins, normal paraffins, naphthenes and olefins. The isoparaffins and any coeluting olefins, normal paraffins and naphthenes are then separated and detected by carbon number. Simultaneously, the individual non-aromatic components are separated and detected. The aromatics that have been previously separated are then individually separated and detected. The apparatus and method may also include a fifth column for detecting quantities of a preselected inorganic compound.
