WebITEM #: 16095957 Through special derivatization techniques, the concentration of the cyclodextrin in the CHIRALDEX B-DM has been substantially increased in the polysiloxane carrier. This phase is very useful for a number of free acids and bases. The B-DM is able to perform most of the separations done on a beta-permethylated phase, but with higher … WebCyclodex-B Columns. Agilent J&W Cyclodex-B is a 10.5% beta-cyclodextrin capillary column that enables chiral separations without requiring chiral-specific derivatization. With the ability to effectively resolve over a broad range and produce excellent peak shapes, these columns provide reliability, repeatability, and sensitivity, for superb ...
