Japan YMC CHIRAL CD-BR chiral column

YMC CHIRAL CD-BR series column includes three optical isomer separation column, the brominated derivative of cyclodextrin covalently bonded silica prepared. YMC CHIRAL CD-BR column to separate the use of host-guest interaction, the selectivity is different from the ODS column. Such brominated cyclodextrin derivatives may be used a water-soluble polar compound isolated using reversed phase mode, in addition they can position substituted aromatic compound isomers separated under similar conditions. ? -cyclodextrin Optical isomer separation column can be used to separate optical isomers and structural isomers of the three types of holes:??
