TSK-GEL Alpha and SuperAW columns were developed for the GPC analysis of polymers of intermediate polarity. As in the PW- and PWxl-type resins, the particles in TSK-GEL Alpha and SuperAW columns have a hydroxylated methacrylate polymer backbone, but they are crosslinked to a higher degree to minimize swelling in polar organic solvents.
TSK-GEL Alpha and SuperAW particles are available in a wide variety of pore sizes.
Use semi-micro TSK-GEL SuperAW columns
- for high-throughput applications
- to reduce solvent consumption
- to reduce solvent disposal cost.
Use TSK-GEL 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).

|
Alpha and SuperAW columns:
Particle sizes
- SuperAW, 4-9 μm particles
- Alpha, 7-13 μm particles
No or minimal swelling in a wide range of polar organic solvents: methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP.
For high thoughput applications, TSK-GEL SuperAW columns provide equivalent resolution in 1/2 the time compared to TSK-GEL Alpha columns.
Accurate MW determination and normal retention of polystrene polymers in DMF solvent.
System peaks from salts in the eluent elute away from the oligomer of interest.
Applications: polymers that are soluble in methanol, acetonitrile, DMSO, isopropanol, or THF; can also be used for water-soluble polymers. | |
