By adding β or γ cyclodextrin to Restek's bonded Rtx®-1701 stationary phase, we 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-ethyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin added into 14% cyanopropylphenyl/86% dimethyl polysiloxane
• Excellent for most chiral compounds in essential oils
• Longer column lifetime
• Improve overall utility
• Ensured stability

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