Due to the very low pKa (< 1) these functions are strong cation exchangers since they maintain a negative charge throughout the pH scale. The most common use is likely for catch and release purification of weak cations (for example basic drugs and analgesics), analysis of basic biomolecules (peptides and proteins) and water-soluble vitamins (basic vitamins B and C).

Packed with SiliCycle’s 25 μm spherical silica gel, SiliaSep PREMIUM flash cartridges will give you better resolution for difficult purifications, sharper peaks, higher loading capacity and faster separations.
