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

Incrprates a phase cnsisting f a 2,3-di-O-ethyl-6-t-butyl silyl derivative f γ-cycldextrin. This phase exhibits brad chiral selectivity, reslving aliphatic, lefenic, and aratic enantiers. This particular diethyl phase has been devised t verlap with the applicatins f bth the PM and PH series f cluns. T date, it has shwn siilar selectivities with shrter retentin ties and greater reslutin. It als has exhibited theral stability equivalent t the PM and is, therefre, the clun f chice when elutin teperature f the analyte exceeds 200°C.

Features:

• Brad chiral selectivity
• Cbines selectivity f PM and PH
• Theral liit t 200/220 °C
• Shrt retentin, high reslutin
• Beta derivative bradly applicable
• Reslves aliphatic, lefenic and aratic enantiers

Mechanis Observatins:

• Size selectivity present but nt dinant as in DA
• Fewer structural requireents
• Characteristic teperature selectivity

Size Selectivity:

Size selectivity is evident; therefre, the inclusin echanis is playing a rle in the separatin echanis but des nt dinate as it des in the DA series. The beta fr as in the PH series cvers a very brad range f lecular sizes and, therefre, has the greatest applicability.
