TSKgel GMPWXL
TSKgel GMPWXL is a mixed bed scouting column for water-soluble linear polymers. The pore volume can be accessed by polymers ranging in molecular weight from 500 to 8 x 10^6 Da.
Mixed bed columns contain a mixture of different pore sizes that have an extended linear calibration range, suitable for samples with a broad molar mass distribution as well as unknown samples. By quickly categorizing the molecular weight profile of an unknown sample, the column enables a fast selection of the best TSKgel PWXL column for routine analysis.
The TSKgel GMPWXL column has a base material of hydroxylated polymethacrylate, can be used in a maximum of 20% organic, and is shipped in water.
