The Most Advanced GPC/SEC Instrument for Polyolefin Analysis

Polymer Char launches its new High Temperature GPC instrument. The GPC-IR is specially designed to polyolefin analysis and provides its users with an advanced modular design, an improved detection
stability and full automation of the analytical process.

The GPC-IR fully automated operation process eliminates the need of solvent handling. The instrument takes care of the filling of the vials, sample dissolution, in-line filtering and injection process. There is no need at all of vials transfer at high temperature.

The GPC-IR main body consists of a columns oven compartment, with a 0.01ºC control up to 220ºC, where the GPC columns are placed and isolated from the rest of the hardware; and on top of it, the
separate Injector-Detectors Oven compartment, where Injection and filtration valves and detectors are installed.

The autosampler’s capability is 70 samples, with a heated zone for sample dissolution. Each sample vial stays at the heated compartment (up to 250ºC) only for selected dissolution time. This capability combined with a gentle shaking avoids the thermal and shear degradation in the samples.

The instrument can be configured as a quadruple detector system with: Infrared detector IR4 (with concentration and composition sensors), Viscometer, Light Scattering (DAWN® HELEOS™ II of Wyatt
Technology) and, optionally the high sensitive IR5 with a Mercury Cadmium Telluride infrared detector can be added for the analysis of very low levels of branching.

GPC-IR Virtual Instrumentation Software provides instrument control and process monitoring. The new and comprehensive GPC One calculation and reporting software platform integrates all detector signals in a single package. Also SQC (Statistical Quality Control) tools are incorporated into the software, to help tracking the status of the instrument.
