Multimode Columns

Print
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
