HPLC Columns


The TSKgel DEAE-NPR column is packed with spherical 2.5 µm, non-porous, high efficiency, hydrophilic polymer beads which are surface modified with a weak anion exchange group. These columns are used for the high speed separation and analysis of proteins and poly- and oligonucleotides. TSKgel DEAE-NPR columns are particularly useful for high resolution separation of DNA digests or fragments.

NPR stands for Non-Porous Resin.
