SUPELCO Astec CHIRALDEX G-BP手性氣相色譜柱 毛細管柱
- CD Type: γ (gamma)
- Derivative: Butyryl
- Temp. Limits: -10 °C to 200 °C (isothermal) or 220 °C (programmed)
Incorporates a phase consisting of a 2,6-di-O-pentyl-3-butyryl derivative of γ-cyclodextrin
This phase has shown its best selectivity for amino acids, certain amines and furan structures. It is a nonpolar phase and has the temperature stability of the alkyl type phases. It is considered a good alternative to the bonded amino phases with much broader separation capabilities.
Features:
- Separates the widest variety of enantiomers
- Gamma most versatile
- High selectivity for amino acids, amines, furansThermally stable
Analytes:
Useful for homologous series of:
- Amino acids (primary, secondary, aromatic and aliphatic)
- Amines (primary, secondary, cyclic, aromatic and halogenated)
- Amino alcoholsAlkanes, hydrogenated alkanes
- Alcohols (aliphatic and aromatic)
- Acids (halogenated and hydroxy)
- Esters (aromatic, aliphatic, hydroxy, di-ester)
- DiolsLactones
- Ketones
- Phthalides
- Sulfoxides
Mechanism Observations:
- Alkyl chain on analyte contributes to chiral recognition
- High sample capacity, therefore, primary surface interactions
Size Selectivity:
For this derivative, gamma-cyclodextrin exhibits a much broader selectivity than beta-cyclodextrin. The influence of the inclusion mechanism on selectivity is much reduced and capacities are, therefore, generally higher. -
