GS-HQ
  • SEC is the main separation mode
  • With the choice of eluent, the column provides multimode features of reversed phase, HILIC, and ion exchange modes to SEC
  • Suitable for the separation of peptides or nucleic acids with similar molecular weights
  • Suitable for desalting samples or substituting buffer in protein analysis
