WebIon-exchange membranes are essentially sheets, ribbons, or tubes which separate two fluids and are capable of ion exchange. It was first discovered and studied by Oswald in 1890 that a membrane can be impermeable to any electrolyte if it is impermeable to either its cation or anion. Webpurification of proteins using ion exchange chromatography? A HiTrap™ 1 mL IEX columns can be used manually together with a syringe. After equilibration, sample application and wash, elution is done gradually by increasing the salt concentration. If you have no way to form a gradient, you can do this using steps of different salt concentrations.

WebChromatography is a technology of choice for large-scale purification processes: Efficient: high purity fractions. Green: no effluents or chemical consumption.
