TSKgel G2500PWxl columns are ideally suited for analysis of water-soluble linear polymers with molecular weights up to 3,000 Da. Because of the presence of cationic groups on the base bead of TSKgel G2500PWxl, this column is not suited for separating anionic polymers. The smaller particle size of TSKgel PWxl-type columns provide 1.7X higher resolution than their TSKgel PW counterpart, making TSKgel PWxl-type columns more suitable for analytical purposes.
