Rt^®-βDEXm:

General-purpose chiral phase with many published applications

Rt^®-βDEXsm:

Excellent column for most chiral compounds in essential oils

Rt^®-βDEXse:

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

Rt^®-βDEXsp:

Often useful in dual-column configurations, with the Rt^®-βDEXsm column, for complex enantiomeric separations

Rt^®-βDEXsa:

Unique selectivity for esters, lactones, and other fruit flavor components

Rt^®-βDEXcst:

Proprietary stationary phase, developed specifically for the fragrance industry
Also used for pharmaceutical applications

Rt^®-γDEXsa:

Suitable for larger organic molecules
Also useful for flavor compounds in fruit juices

Rt^®-2560:

Stationary phase selectivity optimized for isomer separation to ensure accurate quantification of critical cis/trans FAMEs (Fatty Acid Methyl Esters)
Application-specific QC test guarantees consistent, reliable performance for AOAC 996.06 and AOCS Ce 1j-07 methods
Excellent sample capacity; no peak distortion means easy, accurate peak integration

Rt^®-TCEP:

General-purpose columns, ideal for aromatics and oxygenates in gasoline
High polarity provides a retention index for benzene over 1000
Separates alcohols & aromatic compounds from aliphatic components in gasoline
