TSKgel GMHxl

The TSKgel GMHxl column is packed with a mixture of rigid, polymer beads, varying in average pore size, for the analysis of organic-soluble industrial polymers. Mixed bed, or linear columns, are used when a broad range of polymer molecular weights is expected in the sample. This column provides high resolution of polymers with molecular weights of less than 4 × 10⁶ Da.  The main characteristics of the TSKgel GMHxl column are: ultra-low sample adsorption, i.e., the column shows true size exclusion behavior for most polymers, limited solvent range, and a maximum operating temperature of 80 °C.

As the number of solvents that can be exchanged directly with the shipping solvent (THF) of the TSKgel GMHxl column is limited, use TSKgel Hhr columns when a broader range of solvents is needed.
