Supelco DEX Chiral Columns



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.

  • Permethylated cyclodextrins - α-DEX, β-DEX and γ-DEX 110 and 120
  • Diacetylated cyclodextrins - α-DEX and β-DEX 225
  • Dimethylated cyclodextrins - α-DEX and β-DEX 325

Group 2: Surface & Inclusion Interactions, Simple Derivatives...Supelco DEX 225 and 325
Group 3: Inclusion Interactions...Supelco DEX 110 and 120

Supelco DEX columns are available individually, or in convenient and economical kits. Use our Chiral Screening Service to help you choose the right column for your application.
