The TSKgel QC-PAK GFC 200 column is 15 cm in length with 5 μm particles.  This stainless steel column offers the same resolution in half the time as the 30 cm, 5 μm TSKgel G2000SWxl column.

The TSKgel Alpha-2500 column is packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP).  This column is stable in a wide variety of organic solvents at concentrations up to 100%.

The TSKgel Alpha-3000 column is packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP).  This column is stable in a wide variety of organic solvents at concentrations up to 100%. The main application area for the TSKgel Alpha-3000 column is the analyses of polymers that are soluble in polar organic solvents up to 100,000 Da. Examples include cellulose derivatives, polyimide, and sodium dodecylsulfate (all in 10 mmol/L LiBr in DMF), cleansing gel in methanol, and degree of saponification of polyvinylalcohol in hexafluoroisopropanol (HFIP).

The TSKgel Alpha-4000 column is packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP).  This column is stable in a wide variety of organic solvents at concentrations up to 100%. The main application area for the TSKgel Alpha-4000 column is the analyses of polymers that are soluble in polar organic solvents up to 1 x 10⁶ Da. Examples include cellulose derivatives, polyimide, and sodium dodecylsulfate (all in 10 mmol/L LiBr in DMF), cleansing gel in methanol, and degree of saponification of polyvinylalcohol in hexafluoroisopropanol (HFIP).

The TSKgel Alpha-5000 column is packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP).  This column is stable in a wide variety of organic solvents at concentrations up to 100%. The main application area for the TSKgel Alpha-5000 column is the analysis of polymers that are soluble in polar organic solvents up to 7 x 10⁶ Da. Examples include cellulose derivatives, polyimide, and sodium dodecylsulfate (all in 10 mmol/L LiBr in DMF), cleansing gel in methanol, and degree of saponification of polyvinylalcohol in hexafluoroisopropanol (HFIP).

The TSKgel Alpha-6000 column is packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP).  This column is stable in a wide variety of organic solvents at concentrations up to 100%. The main application area for the TSKgel Alpha-6000 column is the analyses of polymers that are soluble in polar organic solvents greater than 10 x 10⁶ Da. Examples include cellulose derivatives, polyimide, and sodium dodecylsulfate (all in 10 mmol/L LiBr in DMF), cleansing gel in methanol, and degree of saponification of polyvinylalcohol in hexafluoroisopropanol (HFIP).
