GPC-IR® Analysis Overview

GPC analyses allow the customer to obtain the molar mass distribution of a polymer resin. They are performed by Polymer Char’s GPC-IR Instrument, which incorporates the best detector for polyolefins, the IR5, which is used as Concentration and Composition detector to obtain the Molar Mass Distribution curve and SCB information.

In addition, other detectors can be attached like Viscometer or Light Scattering to obtain more complete results in MWD, SCB, LCB… or IR5 MCT for an accurate and highly sensitive measurement of the methyls content in pipe HDPE.

A report is sent to the customer with the Molar Mass distribution curve, the analysis conditions used as well as the calculations of Mn, Mw… An Excel file with the raw data can also be sent when required.
