TSKgel GMHhr-M mixed bed columns are packed with rigid, multiple pore size, polymer beads. Mixed bed columns are commonly used for unknown samples and for the analysis of polymers with a broad molecular weight distribution. TSKgel GMHhr-M columns are shipped in THF, which can be exchanged for a wide variety of organic solvents.

TSKgel GMHhr-M columns are available in 5 and 13µm particle sizes.  We recommend the use of TSKgel GMHhr-M(S) (13µm) to prevent or limit shearing of ultra high molecular weight polymers, if this occurs when using small (5µm) particle size columns.
