GEL-PERMEATION CHROMATOGRAPHY CALIBRATION CURVE FOR ASPHALTENES AND BITUMINOUS RESINS

For the determination of molecular-weight distributions by means of gel-permeation chromatography, one needs a calibration curve which relates molecular weight to elution volume. Such a curve has been constructed for high molecular bituminous components by combining the chromaiograms partly with molecular-weight distributions derived from velocity ultracentrifugation, partly with measured average molecular weights. It proved possible to calculate the calibration curve for asphaltenes when that for polymers is known. Benoit's universal calibration curve, in which the product of molecular weight and limiting viscosity number is used as a measure of the hydrodynamic volume, does not apply for asphaltenes.
