Introduction


Q (DEAE, S, CM) SepFast™ HighRes is a group of ion-exchange chromatography media with reduced bead size (20 – 50 μm). They are specially designed for high resolution purification of biological molecules in which impure components are hard to separate by normal bioprocessing chromatography media.

 The core advantages are:

  • High resolution at high loading
  • High sample loading capacity at high flow
  • High productivity

The base matrix of IEX SepFast HighRes is made of highly cross-linked agarose. The media is very stable to most of the chemical conditions experienced in the bioprocessing industry.
