SGIC 2D
The Two-Dimensional Solvent Gradient Interaction Chromatograph (SGIC 2D) instrument performs a fractionation of the polymer according to composition by solvent gradient HPLC technique in adsorption mode followed by a second separation by Gel Permeation Chromatography (GPC/SEC) of the fractions eluted from the first dimension.
Polymer Char’s analytical SGIC 2D instrument is a practical alternative to preparative fractionation methods, which are sometimes tedious and time consuming. The composition – molar mass interdependence is now measured in hours instead of days, with limited solvent consumption and no manual intervention, in an intrinsically safe setup.

Features
Features
- Fully automated instrument to measure the composition – molar mass interdependence of complex and functional Polyolefins.
- Special interest for some polar or low crystallinity Polyolefins.
- Detection performed in isocratic mode: a linear IR detector can be used instead of a non-linear ELSD. Compatible with molar mass sensitive detectors.
- No solvents handling, fully automated process, including in-line filtration.
- Flexible definition of the number of fractions and the solvent gradient profile.
- Bivariate distribution results presented as contour or 3D surface graphs.
- Automated analysis of a sequence of samples, with flexibility to use different methods for each one
