Applying the formalism of averaged elution volumes corresponding to average molecular weights or intrinsic viscosities of polydisperse polymer standards simple, single‐valued equations were developed for iterative evaluation of calibration parameters of both direct and universal GPC calibration relationships. The developed evaluation procedures are simpler and converge faster than corresponding methods described in the literature.
