• CD Type: γ (gaa)
• Derivative: Prpinyl
• Tep. Liits: -10 °C t 200 °C (istheral) r 220 °C (prgraed)

Astec? CHIRALDEX G-PN incrprates a phase cnsisting f a 2,6-di-O-pentyl-3-prpinyl derivative f γ-cycldextrin. This phase exhibits high selectivity fr lactnes and aratic aines. It is als suitable fr epxide separatins. Additinally, the analysis f styrene xide can be accplished n this phase (this analyte degrades n the TA phases).

Features:

• Suitable fr epxide separatins
• High selectivity fr lactnes
• High selectivity fr aratic aines (i.e. aphetaine, ethaphetaine)
• Mre stable t isture than the TA phases

Analytes:

Epxides, aratic aines (aphetaine/ethaphetaine), >C6 alchls and lactnes

Mechanis Observatins:

There is little evidence f inclusin fratin. Retentin increases with increased chain length f analyte. This allws fr efficient separatin f a series f hlgs.

Size Selectivity:

The γ (gaa) fr shws a higher degree f selectivity ver the beta fr fr this phase, and very little selectivity based n cavity size.
