詳細介紹

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. -
