HPLC Columns


TSKgel GMPW are mixed bed scouting columns for water-soluble linear polymers. The pore volume can be accessed by polymers ranging in molecular weight from 500 to 8 x 106  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 PW column for routine analysis. 


Stable from pH 2 to 12, TSKgel GMPW columns can be used in mobile phases of water or buffer (up to 20% methanol/80% aqueous) and can tolerate temperatures up to 80°C.
