Mixed-Mode chromatography

Asahipak™ GS-HQ is an HPLC columns with SEC as the main separation mode. With the choice of eluent, the column provides multimode features of reversed phase, hydrophilic interaction (HILIC) and ion exchange modes to SEC. The columns are suitable for the separation of peptides or nucleic acids with similar molecular weights and for desalting samples or substituting buffer in protein analysis. The base material is Polyvinyl alcohol.
