Mustang® Ion Exchange Membranes

Ion Exchange Membranes Introduction

In many areas, chromatography resins are the media of choice for chromatography applications. In some instances, where resin-based methods have limitations (e.g., purification of viruses or large molecules), membranes have proven to be a robust, scalable, and economical alternative to resins. Chromatography membranes offer faster flow rates as compared to their resin counterparts.

For ion exchange applications (see Table 4.1), Pall offers Mustang ion exchange membrane. This technology is available in several formats including a syringe filter column and a 96-well filter plate.
