YMC CHIRAL CD BR Series

YMC CHIRAL CD BR Series

◈ Product Information
YMC CHRAL CD BR series is composed of 3 types of optical isomer separation columns. Each column possesses α-,β-,or γ-bromo-cyclodextrin as a functional group. Selection from the 3 types of columns enables analysis of a wide range of compounds. In addition, YMC CHIRAL CD BR series shows different selectivity from ODS because the separation is based on host-guest interaction. YMC CHIRAL CD BR series is useful for separating structural isomers that are difficult to separate using ODS.

α-CD BR,β-CD BR,γ-CD BR show different separation feature because each of them has different size of cavities. Therefore choosing proper one can result in providing a successful separation of a wide-range compounds. It is also effective to use together with ODS columns.

YMC CHIRAL CD BR series provide better separation for various optical isomers because cyclodextrin is a chiral compound. YMC CHIRAL CD BR series is effective as a chiral column for reversed phase eluent.
