On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.
Sepax Technologies Inc Sepax HPLC Column Carbomix Ca-NP10, 10% Crosslinkage, 4.6 x 300 mm
Carbomix phases are composed of spherical, low cross-linking polystyrene/divinylbenzene (PS/DVB) particles with their surfaces modified with sulfonic acid (-SO3H), followed by chelating of metal ions of calcium (Ca2+), lead (Pb2+), sodium (Na+) or potassium (K+) to form Carbomix Ca-NP, Pb-NP, Na-NP, K-NP phases, respectively. The PS/DVB support has cross-linking degree of 5%, 8% and 10% with the particle sizes of 5 and 10 µm. The uniform particle size adds the benefit of high separation efficiency to Carbomix. Carbomix resins have been specifically designed for high resolution separation of carbohydrates, organic acids, peptides, and nucleic acids.
Sepax Technologies Inc Sepax HPLC Column HP-SCX, 10 µm, 120 Å, 10 x 150 mm
HP-SCX is a silica based mixed-mode strong cation exchange phase. The phase has a mixed chemical structure of sulfonic acid and phenyl group. The mixed mode of strong cation-exchange and hydrophobicity offers unique selectivity and high resolution separation for cationic/basic and nitrogen containing compounds as well as desirable retention for a variety of weak cationic and neutral organic compounds. The uniform polymeric bonding of HP-SCX enhances its stability under various separation conditions.HP-SCX has expanded its applications from the traditional SCX separation of cationic and nitrogen containing compounds to weak cationic and neutral organic molecules. Examples include separation of analytes of amines and polyamines, such as alkaloids, peptides, codeine, and cough and cold ingredients.
