Abstract

A Sephadex G-100 column with an AutoAnalyzer detector was used in order to characterize a long-chain polyphosphate mixture. This technique enabled us to obtain the molecular weight distribution profile of the mixture within 2 h. A linear relationship between distribution coefficient values and the logarithms of the average chain lengths was obtained.
