Abstract
The numerical treatment of a chromatogram to obtain the various molecular weight averages is discussed. The method used by Cooper and Matzinger to calculate the influence of the number of data points on Mn and Mw, is criticized. Another model function is proposed. Calculations then show that the results obtained for Mn, Mw and Mz are approaching the theoretical values more and more by increasing the number of data points as it should be expected. This is in contradiction with the results of Cooper and Matzinger. The influence of the base-line correction is evaluated too.Keywords
