A study of measurement of the Molecular weight average (Mw) of Gelatin

Abstract

In order to calculate the molecular weight average of Gelatin, current HPLC method for measuring the molecular weight distribution was re-examined. To this end, desirable Test methods contains a new Separation HPLC column and elution conditions. According to this new test method, the void area disappeared and confirmed a molecular size separation by Sec-MALS. The Molecular weight average (Mw) of several gelatins were measured according current and new test methods and compared.
