Astec CHIRALDEX B-PH SUPELCO 手性氣相色譜柱 毛細管柱
- 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
