  • 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. -
