TSKgel Alpha-4000
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…

Does what it should do.
Analyzing polymers
The column needs some time to reach its full potential, at the beginning the values fluctuated a bit. In the meantime, everything has worked wonderfully. The column separates what it should separate. There are no problems. It is now three months in use.

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 10^6 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).
