Welchrom Phenyl

Welchrom® Phenyl formed by Phenyl SPE bonded stationary phase, and its SPE column packing mterials increase the unique polar forces of the benzene ring and improves the retention ability of alkaline compounds. When aromatic compounds and non-aromatic compounds are extracted together, a different selectivity than C18, C8 and other reversed-phase of Welchrom® Phenyl is manifested. Welchrom® Phenyl based on silica gel has an average particle size of 45μm, pore diameter of 60Å, pore volume of 0.80cm3/g, surface area of 480m2/g
