Abstract
The present invention is generally related to the analysis of chemical compositions of hydrocarbons and hydrocarbon blends. This method, in particular embodiments, may apply specifically to the problem of analyzing extremely complex hydrocarbon-containing mixtures when the number and diversity of molecules makes it extremely difficult or impossible to realistically identify and quantify them individually in a reasonable timeframe. Particular SEC (size exclusion chromatography)-based methods and apparatus disclosed herein may be used to measure, e.g., the molecular size, weight, and/or volume, whether in absolute or relative manner, of the various components of eluate from the SEC stationary phase (e.g., a permeable gel). This analytical method is applicable on a wide variety of hydrocarbonaceous materials, and especially useful for, but not limited to oil, maltenes of oil, asphalt binders and asphalt binder blends, which may contain wide varieties of different types of additives, modifiers, and chemistries.
