Shodex: Packed Columns for HPLC Analysis

Columns for GPC Clean-up

Pretreatment using GPC columns (GPC clean up series) is carried out in the analysis of a sample, such as a food ingredient, with a complex matrix in order to remove lipids and other high molecular weight compounds and pigments. Shodex CLNpak is a GPC clean up column that is packed with rigid polymer-based gel with minimal shrinkage. A wide range of eluent is made possible by using rigid polymer-based gel material.
