Notes:
The method of Balke, Hamielec, LeClair, and Pearce for GPC calibration and molecular weight computation is reviewed and evaluated. A new method, called GPCV2, is proposed which uses the single broad molecular weight distribution (MWD) standard for calibration developed by those workers, but which also incorporates the chromatographic dispersion σ to make the method more accurate in general use. Equations are presented for computing the relationship between actual MW and retention volume VR under the chromatographically broadened curves. This relationship is then compared to those obtained by using the Balke et al. method and the peak position method.
