METHOD FOR MEASURING CONCENTRATION AND MOLECULAR WEIGHT DISTRIBUTIONS OF GLUE AND GELATIN

摘要

PROBLEM TO BE SOLVED: To provide a method for effectively measuring concentration and molecular weight distributions of a glue and a gelatin in a liquid or particularly the glue and the gelatin each having a low molecular weight. SOLUTION: The method for measuring the concentration and molecular weight distributions of the glue and the gelatin contained in an electrolyte comprises the step of measuring the concentration and molecular weight distribution of the glue and the gelatin by a high-performance liquid chromatograph in association with a column switching method.
