Astec chiraldex g-bp gc column 30 m 0,25 mm

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:
Gamma most versatile
High selectivity for amino acids, amines, furans
Thermally stable
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.
