Benzenesulphonic acid modified silica cation exchanger for SPE (SCX)
Base material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, benzenesulphonic acid modified silica, strongly acidic cation exchanger (capacity 0.5meq/g). Adsorbent with hydrophobic and interactions (benzene ring). Ion exchange of organic compounds from aqueous matrix. Elution of interesting compounds with solvent systems, which compensate the ionic and nonpolar interactions, e.g. methanolic HCl.
Recommended application: amino acids, amines, chlorophyll, PCB.
