Column Packing
MilliporeSigma™ Supelco™ Discovery™ DSC-WCX SPE Bulk Packing
Typically used when dealing with very strong cationic (high pKa) compounds that may be irreversibly retained on strong cation exchangers·
MilliporeSigma™ Supelco™ AmberChrom™ (formerly Dowex™) 50WX2 Hydrogen Form, 100-200 mesh
A preferred strong cationic exchange (SCX) resin due to its attractive features such as high capacity, easy availability and ease of operation owing to the lower degree of divinylbenzene cross-linking leading to higher recoveries of aromatic amino acids.
