A polysaccharide coated chiral stationary phase and columns which are produced using a unique production process of coating the proven chiral selector, tris-(3,5-di- methylphenyl) carbamoyl amylose on high purity silica gel. ChromegaChiral CCA columns, similar in selectivity to ChiralPak® AD, are available in 3, 5, 10, and 20 micron particle sizes enabling easy scale up from analytical to preparative scale using HPLC or SFC conditions.
