• CD Type: β (beta)
• Derivative: S-Hydrxyprpyl
• Tep. Liits: -10 °C t 200 °C (istheral) r 220 °C (prgraed)

Incrprates a phase cnsisting f a (S)-2-hydrxy prpyl ethyl ether derivative f β-cycldextrin. This phase separates a wide variety f enantiers, reslving aliphatic, lefinic, and aratic enantiers. It is a gd general purpse chiral clun.

The first general purpse derivative invlved substitutin f the cycldextrin hydrxyl grups with pure "S" hydrxyprpyl fllwed by perethylatin. The surface is hydrphilic in character and the influence f size and shape selectivity is greatly reduced but nt absent. The beta-cycldextrin* fr has the bradest applicability.

Features:

• Hydrphilic surface
• Beta is re selective than alpha
• Separates a wide variety f enantiers
• Reslves aliphatic, lefinic and aratic enantiers
• Gd general purpse chiral clun

Mechanis Observatins:

• Reduced influence f inclusin cplexing
• Less size selectivity fr PH as ppsed t DA
• Teperature range fr enantieric selectivity: Istheral t 200°C; teperature prgra t 220°C
• Characteristic teperature selectivity n a given clun fr a given class f cpunds
• Fewer functinal requireents fr analyte than LC
