SUPELCO Astec CHIRALDEX G-BP手性气相色谱柱 毛细管柱

CD Type: γ (gamma)Derivative: ButyrylTemp. 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 enantiomersGamma most versatileHigh 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 alkanesAlcohols (aliphatic and aromatic)Acids (halogenated and hydroxy)Esters (aromatic, aliphatic, hydroxy, di-ester)DiolsLactonesKetonesPhthalidesSulfoxides

Mechanism Observations:

Alkyl chain on analyte contributes to chiral recognitionHigh 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. -
