详细介绍

SUPELCO Astec CHIRALDEX G-DM手性气相色谱柱毛细管柱

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

Incorporates a phase consisting of a 2,3-di-O-methyl-6-t-butyl silyl derivative of γ-cyclodextrin. This phase exhibits broad chiral selectivity, resolving aliphatic, olefenic, and aromatic enantiomers. This particular dimethyl phase has been devised to overlap with the applications of both the PM and PH series of columns. To date, it has shown similar selectivities with shorter retention times and greater resolution. It also has exhibited thermal stability equivalent to the PM and is, therefore, the column of choice when elution temperature of the analyte exceeds 200°C.

Features:

Broad chiral selectivity
Combines selectivity of PM and PH
Thermal limit to 200/220 °C
Short retention, high resolution
Beta derivative broadly applicable
Resolves aliphatic, olefenic and aromatic enantiomers

Mechanism Observations:

Size selectivity present but not dominant as in DA
Fewer structural requirements
Characteristic temperature selectivity

Size Selectivity:

Size selectivity is evident; therefore, the inclusion mechanism is playing a role in the separation mechanism but does not dominate as it does in the DA series. The beta form as in the PH series covers a very broad range of molecular sizes and, therefore, has the greatest applicability.
