The inventive technology may involve, in particular embodiments, novel use of a non-porous, high surface energy stationary phase to adsorb, in reversible fashion, the most polar component of a resins fraction of an input hydrocarbon when a mobile phase is passed over the stationary phase. Such reversible adsorption prevents irreversibly adsorption of such components on active stationary phase(s) downflow of the non-porous, high surface energy stationary phase, thereby conserving stationary phase costs and increasing resolution of resins elutions, and accuracy of hydrocarbon component results. Aspects of the inventive technology may also involve a novel combination of a solubility based asphaltene component fractionating and analysis method and an adsorption chromatography method for separating and/or analyzing saturate, aromatics and resins components of an input hydrocarbon.
