GRAM Columns
GRAM columns can be used for organic GPC and SEC polymer analysis in polar organic solvents. These polyester copolymer-based GPC columns are available in a range of porosities, from 30 to 10,000 Å, and one linear/mixed-bed version to meet the needs for a variety of polymers with molar masses ranging from 100 to 50,000,000 Da, including for the analysis of polyurethane, polyimide, starches, cellulose, and other polar polymers.
