β-DEX 225 GC capillary chiral column
CD Type: β (beta)
Derivative: Diacetyl
Phase: Non-bonded; 25% 2,3-di-O-acetyl-6-0-TBDMS-β-cyclodextrin embedded in SPB-20 poly(20% phenyl/80% dimethylsiloxane)
Temp. Limits: 30 °C to 230 °C (isothermal or programmed)
The chiral stationary phase in β-DEX 225 columns contains 2,3-di-O-acetyl-6-0-TBDMS-β-cyclodextrin embedded in an intermediate polarity phase. These columns provide unique selectivity for enantiomeric separations of small molecules: alcohols, aldehydes (e.g., 2-phenylpropionaldehyde), esters (e.g., methyl malate, methyl lactate), flavor compounds, and ketones.
