(2,3-di-O-ethyl-6-O-tert-butyl dimethylsilyl ß cyclodextrin doped into 14% cyanopropylphenyl/86% dimethyl polysiloxane)

GC columnBy adding ß or y cyclodextrin to our bonded Rtx®-1701 stationary phase, we greatly enhance overall utility and column lifetime for the chiral columns, compared to columns that have pure cyclodextrin stationary phases. Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and our columns continue to demonstrate stability after hundreds of temperature program cycles. Refer to the applications section of this catalog for examples, or call our Technical Service chemists for assistance in matching a column to your chiral analysis.

  • Similar in performance to Rt™-ßDEXsm but provides better resolution for limonene, linalool, linalyl acetate, ethyl-2-methylbutyrate, 2,3-butane diol, and styrene oxides.
