Opis ogólny
The LC-SCX cation-exchange columns have strongly acidic propylsulfonic acid groups and are used for separating cations. Adjust pH, ionic strength, and organic modifier concentration to control retention and selectivity.
Zastosowanie
Supelcosil™ LC-SCX HPLC column was used during the purification and characterization of 8-hydroxyguanine (oh8Gua), from Human Urine.[1] It was used as a cation exchange column, during measurement and extraction of water-soluble arsenic, freeze-dried marine animal tissues, using high performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS).[2] It was also used in the chromatographic separation of arsenic compounds.[3]
