CD Type: β (beta)
Derivative: S-Hydroxypropyl
Temp. Limits: -10 °C to 200 °C (isothermal) or 220 °C (programmed)

Incorporates a phase consisting of a (S)-2-hydroxy propyl methyl ether derivative of β-cyclodextrin. This phase separates a wide variety of enantiomers, resolving aliphatic, olefinic, and aromatic enantiomers. It is a good general purpose chiral column.

The first general purpose derivative involved substitution of the cyclodextrin hydroxyl groups with pure "S" hydroxypropyl followed by permethylation. The surface is hydrophilic in character and the influence of size and shape selectivity is greatly reduced but not absent. The beta-cyclodextrin* form has the broadest applicability.

Features:

Hydrophilic surface
Beta is more selective than alpha
Separates a wide variety of enantiomers
Resolves aliphatic, olefinic and aromatic enantiomers
Good general purpose chiral column

Mechanism Observations:

Reduced influence of inclusion complexing
Less size selectivity for PH as opposed to DA
Temperature range for enantiomeric selectivity: Isothermal to 200°C; temperature program to 220°C
Characteristic temperature selectivity on a given column for a given class of compounds
Fewer functional requirements for analyte than LC
