1. In ion-exchange chromatography the selectivity coefficient is defined in a slightly different way 2. It is usually followed by anion-exchange chromatography using 6 molar HCl as eluant. 3. This distinguishes HILIC as a mechanism distinct from ion exchange chromatography . 4. EDTA was used in the separation of the lanthanide metals by ion-exchange chromatography . 5. These can be separated by ion exchange chromatography . 6. Cation exchange chromatography has been shown to effectively purify ?-interferon . ( Dembinski, et al .) 7. In addition, the effectiveness of the ion-exchange chromatography method helps to differentiate between TcdA and TcdB. 8. Back in Uppsala he developed methods for zone electrophoresis and ion exchange chromatography for hormone purification. 9. Insoluble microgranular CMC is used as a cation-exchange resin in ion-exchange chromatography for purification of proteins. 10. Examples of operations include affinity, size exclusion, reversed phase chromatography, ion-exchange chromatography , crystallization and fractional precipitation.
