ABSTRACT:
The purpose of the present invention is to provide a method to more easily analyze the concentration of glue in an electrolyte solution, while suppressing the degradation of glue during the analysis. There is provided a method for analyzing the concentration of glue contained in an electrolyte solution containing the electrolyte components by using high performance liquid chromatography, where said method comprises a step wherein an electrolyte solution is added into the eluent pH of which has been adjusted equal to or less than 5 by adding acid to an aqueous solution of phosphate of alkaline metal or alkaline earth metal, a step wherein the eluent into which the electrolyte solution has been added is passed through a separation column the exclusion limit molecular weight of which is 4000-6000 for separating the glue and electrolyte components, and a step wherein the separated glue is detected by a detector.
