TSKgel SuperAW Columns

Designed for ultra-high-speed SEC, this series comprises semi-micro columns (6.0 mm ID × 15 cm L) packed with a micro particulate gel based on a hydrophilic vinyl polymer. As the high-strength gel does not show significant expansion or contraction in the presence of different types of solvent, the columns can be used with a wide range of solvents, from aqueous solution to organic solvents. The analysis time is half that of a conventional column (7.8 mm ID × 30 cm), with solvent consumption 1/3 that of a conventional column, while achieving equal separation.

TSKgel SuperAW columns are used for high efficiency and high speed analysis of polymers that are soluble in polar organic solvents. Examples include cleansing gel in methanol, degree of saponification of polyvinylalcohol in HFIP, and sodium dodecylsulfate, polyimide, and cellulose derivatives in DMF with 10 mmol/L LiBr. TSKgel SuperAW columns contain highly crosslinked hydroxylated polymethacrylate particles which minimize swelling in polar organic solvents.

For high throughput applications, the smaller dimensions of the TSKgel SuperAW columns provide equivalent resolution in half the time and with minimal solvent waste compared to the TSKgel Alpha columns. They are ideally used with EcoSEC GPC systems which are optimized for semi-micro SEC/GPC applications.

Mixed bed TSKgel SuperAW Column

The mixed bed column, TSKgel SuperAWM-H, has an extended linear calibration range, and is suitable for samples with a broad molar mass (MM) distribution as well as samples with unknown molecular mass.
