摘要： PROBLEM TO BE SOLVED: To provide a measuring method of concentration and molecular weight distribution of glue and gelatin in liquid, especially glue and gelatin of low molecular weight.
SOLUTION: In this measuring method, the concentration or molecular weight distribution of the glue or the gelatin contained in an electrolytic solution containing an electrolyte component using high-speed liquid chromatography. The glue or gelatin is separated from the electrolyte component in the electrolytic solution using a pretreatment column as a column of high-speed liquid chromatography. The liquid containing the glue or gelatin with the electrolyte component separated is introduced into another column filled with a filling agent of size exclusion mode, and the glue or gelatin is separated according to the molecular weight or molecular weight distribution. The liquid containing the separated glue or gelatin is subsequently introduced into a detector.
