1. Introduction
Thank you for purchasing the Shodex product. Shodex Asahipak GS-220 20G and GS-320 20G are polymer-
based size exclusion chromatography (SEC) columns. With the choice of eluent, the column provides multimode
features of reversed phase chromatography, hydrophilic chromatography (HILIC), and ion exchange
chromatography in addition to SEC. The column series is suitable for the separations of peptides or nucleic
acids with similar molecular weights.
