GPC - Gel Permeation Chromatography Extension
GPC - Gel Permeation Chromatography Extension
Extension provides interactive and automated GPC analysis, including recalibration and GPC reporting, as well as simplifies the retrieval of GPC data.
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.
Main features
| 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. |
| Narrow, Broad, Broad on Narrow standard calibration methods combined with Flow Rate correction and Universal calibration. Manual calibration or automated recalibration from a sequence. Multiple Broad standards can be used. | |
| GPC Calculations | Polynomial (n= 1-5) curve fits (independent for signals), Mp, Mn, Mw, Mv, Mz, Mz+1 molecular weight averages and polydispersity. |
| Graphs | Molecular weight distribution graphs. Overlay: Simultaneously displays a virtually unlimited number of chromatograms. Overlay of dW/d logM vs. log M and cumulative height graphs. |
| Export | Slice Table results, graphs, result and summary tables. |
| User Calculations | Users can define custom calculations in the Result and Summary tables. Using the integrated editor, you can create your own columns from the original columns and individual mathematical functions. |
| GPC Results Table | Displays molecular weight averages together with peak details for active signal. Multiple peaks can be evaluated from one chromatogram. |
| GPC Summary Result Tables | Displays and prints selected results from all simultaneously displayed chromatograms. Postrun: Automatically displays, prints, exports, and starts other programs after the completion of a measurement. |
| Batch | Automatically batch processes, displays, exports, or prints any number of chromatograms. |
| Reports | User selectable report sections and WYSIWYG formating of Graphs and Tables. |
