Detection of a Trace Amount of a Super High Molecular Weight Component
by Triple Detection Gel Permeation Chromatography (3D-GPC)

Print

Summary

The light scattering particle detector (LS) incorporated into 3D-GPC equipment is capable of detecting a trace amount of a super high molecular weight component that cannot be detected by a refractive index meter (RI) that is in general use. This makes a difference between resins showing delicately different flowability clear and makes it possible to determine the cause of unsatisfactory molding processing in some cases.

3D-GPC equipment

The GPC column within the equipment kept at high temperature (140℃) separates the particles according to size, which are detected by three types of detector.

Main objects of measurement are olefin-based polymers.
