By adding β or γ cyclodextrin to Restek's bonded Rtx®-1701 stationary phase, greatly enhance overall utility and column lifetime for Restek's chiral columns, compared to columns that have pure cyclodextrin stationary phases.

• 2,3-di-O-propyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin added into 14% cyanopropylphenyl/86% dimethyl polysiloxane
• Improved column lifetime
• Enhanced column utility

Separations of more than one hundred chiral compounds have been achieved using Restek's unique DEX columns, and Restek's columns continue to demonstrate stability after hundreds of temperature program cycles.

Uses: Often useful in dual-column configurations, with the Rt-βDEXsm column, for complex enantiomeric separations.
