  • CD Type: γ (gamma)
  • Derivative: Propionyl
  • Temp. Limits: -10 °C to 200 °C (isothermal) or 220 °C (programmed)

    Astec? CHIRALDEX G-PN incorporates a phase consisting of a 2,6-di-O-pentyl-3-propionyl derivative of γ-cyclodextrin. This phase exhibits high selectivity for lactones and aromatic amines. It is also suitable for epoxide separations. Additionally, the analysis of styrene oxide can be accomplished on this phase (this analyte degrades on the TA phases).

Features: 

  • Suitable for epoxide separations
  • High selectivity for lactones
  • High selectivity for aromatic amines (i.e. amphetamine, methamphetamine)
  • More stable to moisture than the TA phases

Analytes:

Epoxides, aromatic amines (amphetamine/methamphetamine), >C6 alcohols and lactones

 

Mechanism Observations:

   There is little evidence of inclusion formation. Retention increases with increased chain length of analyte. This allows for efficient separation of a series of homologs.

Size Selectivity:

   The γ (gamma) form shows a higher degree of selectivity over the beta form for this phase, and very little selectivity based on cavity size.
