SUPELCO Astec CHIRALDEX B-PH手性气相色谱柱 毛细管柱
CD Type: β (beta)Derivative: S-HydroxypropylTemp. 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 surfaceBeta is more selective than alphaSeparates a wide variety of enantiomersResolves aliphatic, olefinic and aromatic enantiomersGood general purpose chiral column
Mechanism Observations:
Reduced influence of inclusion complexingLess size selectivity for PH as opposed to DATemperature range for enantiomeric selectivity: Isothermal to 200°C; temperature program to 220°CCharacteristic temperature selectivity on a given column for a given class of compoundsFewer functional requirements for analyte than LC
