DataApex Clarity GPC Extension mass spectrometer and chromatography parts and accessories

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.

The GPC Extension is optional add-on software for the Clarity Chromatography Station (starting from version 2.3) and Clarity Offline. The GPC mode is available to any Instrument within the software.

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.

GPC Calibrations
Narrow, Broad, Broad on Narrow standard calibration methods combined with Flow Rate correction and Universal calibration. Manual calibration or automated recalibration from 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.

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.

Slice Table results, graphs, result and summary tables.

User Calculations
User 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.

Automatically batch processes, displays, exports or prints any number of chromatograms.

User selectable report sections and WYSIWYG formating of Graphs and Tables.
