GPC - Gel Permeation Chromatography Extension | A28

Gel Permeation Chromatography (GPC) / Size Exclusion Chromatography (SEC) is the technique used for obtaining a rapid and reliable characterization of polymer molecular weight and molecular weight distribution. GPC Extension provides interactive and automated GPC analysis, including recalibration and GPC reporting, as well as simplifies the retrieval of GPC data. The GPC Extension allows flow rate and multi-detector delay corrections and includes Narrow, Broad, and Broad on Narrow calibrations.

Data Acquisition: Simultaneous data acquisition from up to four four-detector chromatographs (4×4 configuration), detector delay correction for multidetector measurement. Data Processing: The same chromatograms can be evaluated in both standard and GPC modes. Multiple peaks and multiple signals are processed in one chromatogram.

GPC Integration: Separate integration tables for GPC and standard evaluation are used. There are extensive possibilities for modifying chromatograms. The chromatogram integration can be changed by entering global parameters or interactively, through the direct graphical modification of the baseline.
