Through our Supelco DEX series, we offer a broad range of GC chiral stationary phases (CSPs) with enantioselectivities that are complementary to our CHIRALDEX phases. Both lines are based on derivatized α, β or γ cycloDEXtrin. Supelco DEX columns use dimethyl, diacetyl and tertbutyldimethylsilyl (TBDMS) derivatives and are used to separate volatile chiral molecules, including alcohols, aldehydes, carboxylic acids, epoxides, esters and halogenated compounds. The three derivative types give ten unique GC CSPs
