Use of “Sephadex” Gel for the Estimation of Molecular Weight of Humic Substances in Natural Water

Nature volume 208, pages 1091–1092 (1965)Cite this article

Abstract

THOUGH little is actually known about the shape of humus molecules, and only a few experiments have been described1,2 on the fractionation of humus on ‘Sephadex’ gel (Pharmacia, Uppsala, Sweden), there is strong evidence for the existence of a relationship between the elution rate through the ‘Sephadex’ column and the molecular weight3,4.
