GPC-QC
GPC INSTRUMENT FOR QUALITY CONTROL / PROCESS CONTROL

Simplified and fully-automated GPC instrument
aimed at control laboratories in polyolefin
production plants.

Traditionally, some physical parameters related to an average
of the MMD, such as melt flow index (MFI) and density, have
been used in the industry for quality control. These parameters
are not enough when producing complex multiple reaction
products some of them having multimodal MMD. It is in these
occasions where GPC-QC can provide an important value by
measuring the whole MMD.

KEY FEATURES
Full automation of the entire analytical process.
One sample analyzed in 30 minutes including dissolution.
IR4 or IR5 MCT detectors for Concentration and Short Chain Branching
information.
Optional incorporation of a dual-capillary viscometer.
Simple and reliable design for Quality Control environments.
Comprehensive results (MMD, SCB, IVD).
Outstanding repeatability thanks to the full automation and the detectors
feasibility.

GPC-QC delivers the complete Molar Mass Distribution for one
sample through a simplified workflow, while keeping a fully
automated sample preparation and an analysis free of manual
solvent handling throughout the entire process. The complete
analysis takes 30 minutes including dissolution.

Moreover, for a truly complete analysis, the instrument can
measure intrinsic viscosity by means of a built-in dual capillary
viscometer that can be incorporated optionally.

The IR detection implemented in the instrument through
Polymer Char’s integrated IR4 or IR5 MCT detectors, is highly
stable, contributing to the overall reliability. The IR detector
also provides simultaneous chemical composition information,
which is key for controlling the production of heterogeneous
resins.
