TSKgel Alpha-type
TSKgel™ columns, manufactured by Tosoh Bioscience Incorporate an extensive range of columns with either silica or polymer packings.
TSKgel™ Alpha and SuperAW columns are designed for size exclusion chromatography and based on highly crosslinked polymethacrylate. The columns are compatible with a wide range of solvents (from 100% water to 100% non-polar organic solvents) and were developed for the GPC analysis of polymers of intermediate polarity, soluble in water, buffers and many organic solvents. Compared to the TSKgel™ Alpha columns, the SuperAW columns have partly smaller particle sizes and are provided in smaller column dimensions. This enables fast and high performance analyses.
