TSKgel Alpha and SuperAW columns were developed for the GPC analysis of polymers of intermediate polarity. As in the TSKgel PW- and PWxl-type resins, the particles in TSKgel Alpha and SuperAW columns have a hydroxylated methacrylate polymer backbone, but they are crosslinked to a higher degree than TSKgel PW- and PWxl-type columns to minimize swelling in polar organic solvents.
TSKgel Alpha and SuperAW particles are available in a wide variety of pore sizes.
- Use semi-micro TSKgel SuperAW columns
- for high-throughput applications
- to reduce solvent consumption
- to reduce solvent disposal cost.
- Use TSKgel Alpha columns
- when analysis time is not critical
- when sample mass is not limited
- to collect fractions
- to obtain maximum number of plates (at the expense of analyis time).

Highlights:
Applications: polymers that are soluble in methanol, acetonitrile, DMSO, isopropanol, or THF; can also be used for water-soluble polymers. |
