Agilent J&W CP-Chirasil-Dex CB consists of cyclodextrin directly bonded to dimethylpolysiloxane. This bond prevents the cyclodextrin from migrating to different locations in the surface film, delivering homogeneous enantioselectivity throughout the phase, which provides the highest resolution factor between isomers. It also guarantees stability of enantioselectivity. As a result, the lifetime of β-cyclodextrin capillary columns is significantly improved. CP-Chirasil-Dex CB permits low elution temperatures of polar compounds and is suitable for all injection techniques.
