-
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. -
