The determination of the Mark-Houwink constants using gel permeation chromatography data, based on a known universal calibration dependence and the recorded chromatograms of one or several characterized polydisperse polymer samples, has been modifies by including correction factors for the longitudinal spreading. Verification by means of artificial, computer generated chromatograms shows that the new procedure considerably raises the accuracy and reliability of the results obtained.
