α-DEX 120

CD Type: α (alpha)
Derivative: Permethylated
Phase: Non-bonded; 20% permethylated α-cyclodextrin in SPB-35 poly(35% diphenyl/65% dimethylsiloxane) phase
Temp. Limits: 30 °C to 230 °C (isothermal or programmed)

A small internal cavity in the permethylated α-cyclodextrin generates the molecule′s rigid nature and unique chiral selectivities. These columns have a high shape selectivity for positional isomers (e.g. xylenes, menthols, cresols, substituted-phenols, substituted benzenes) and epoxide enantiomers.
