Ion Exchange Chromatography MIT OpenCourseWare

In an ion exchange column, the stationary phase is a resin on which a usually organic coating provides a charged surface. The mobile phase is a solution with which the ions to be separated are introduced into the system aqueous acid and base solutions, and organic, non-aqueous solutions can be used as the mobile phase. The resin typically
