摘要： The present invention is generally related to the analysis of chemical compositions of hydrocarbons and hydrocarbon blends. This method applies specifically to the problem of analyzing extremely complex hydrocarbon-containing mixtures when the number and diversity of molecules makes it impossible to realistically identify and quantify them individually in a reasonable timeframe and cost. The advantage to this method over prior art is the ability to separate and identify chemical constituents and solvent fractions based on their solvent-solubility characteristics, their high performance liquid chromatographic (HPLC) adsorption and desorption behaviors, and their interactions with stationary phases; and subsequently identify and quantify them at least partially using various combinations of non-destructive HPLC, destructive HPLC, and stand-alone detectors presently not routinely used for HPLC but reconfigured to obtain spectra on the fly. This analytical method is especially useful for, but not limited to, asphalt binders and asphalt binder blends, modified asphalts, asphalt modifiers, asphalt additives, polymer-modified asphalts, asphalts containing rejuvenators and softening agents, asphalts containing recycled products, aged asphalts, and air-blown asphalts, which may contain wide varieties of different types of additives and chemistries, and forensic applications, and environmental pollutant identification.
