Shinwa Xinhe ultron-es-ovm 150x4.6mm chiral chromatographic column es-ovm.1546 has a particle size of 5um and a pore size of 120 À. The chiral stationary phase is ovomyosin (chiral stationary phase brick No. us: 6027648). Ovomyosin is chemically bonded on the surface of silica gel, which conforms to USP L57. Shinwaxin and ultron-es-ovm 150x4.6mm chiral chromatographic column es-ovm.1546 packing has many chiral recognition sites, which makes the column suitable for a wide range of enantiomeric compounds separation, can be used for trace analysis, is a special chiral column for clopidogrel bisulfate, water can be used as the mobile phase.
