WebThe difference is in the functional groups on the SPE phase and their charge state. The strong ion exchange phases are called “strong” because the sulfonate cation or … WebWeakly binding proteins elute first, and stronger binding proteins elute last (i.e. they require higher salt concentrations in the buffer to compete them off the column) A gradient salt concentration can be made using a gradient maker.
WebThe Ion Exchange Demineralisation Process (Strongly functional Resins) • Strong acid cation resins (SAC) exchange H + ions with cation portion of TDS and are regenerated by dilute acid solution (H +) – Water becomes decationised resulting in a solution of weak and strong acids • Strong base anion resins (SBA) exchange OH-ions with anion WebAnion Exchanger vs. Cation Exchanger. The net charge of the molecule(s) of interest determines resin choice. If positively charged molecules are to be immobilized by the column resin, a cation exchange resin is chosen, …

"Weak" ion exchangers have a range of pH values in which they will maintain their charge. If the pH of the buffer used for a weak ion exchange column goes out of the capacity range of the matrix, the column will lose its charge distribution and the molecule of interest may be lost.
