The document introduces an analysis method for modified polyacrylamide using aqueous SEC and triple detection.
The document details a method to analyze modified polyacrylamides, commonly used as flocculants in water treatment and other industries. The goal is to obtain an accurate molecular weight without requiring column calibration by using triple detection technology.
The analysis was performed using an Agilent PL-GPC 50 Plus integrated GPC system equipped with a differential refractive index detector, a viscometer, and dual angle light scattering detectors. Specific columns used were the Agilent PL aquagel-OH MIXED-H 8 um.
