A method and apparatus for conducting chromatographic analysis of a total vacuum resid sample to provide quantification of eight classes of compounds (i.e., asphaltenes, saturates, 1-4- ring aromatics, sulfides, and polars) contained within the total vacuum resid without prior de-asphalting are disclosed (in a first operating mode comprising columns 10, 20, 30). The apparatus is also capable of conducting chromatographic analysis of vaccum gas oils and de-asphalted oils to provide quantification of seven classes of compounds (i.e., saturates, 1-4+ ring aromatics, sulfides, and polars) (in a second operating mode comprising columns 20 and 30). The apparatus is also capable of conducting chromatographic analysis of a resid to identity the presence of and provide quantification of asphaltenes (in a third operating mode comprising column 10).
