TSKgel GMHhr-H 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-H columns are shipped in THF, which can be exchanged for a wide variety of organic solvents.

TSKgel GMHhr-H columns are available in 5, 13, 20, and 30µm particle sizes. We recommend the use of TSKgel GMHhr-H (13, 20 or 30µm) to prevent or limit shearing of ultra high molecular weight polymers, if this occurs when using small (5µm) particle size columns.
