詳細介紹

SUPELCO Astec CHIRALDEX B-PM手性氣相色譜柱毛細管柱

CD Type: β (beta)
Derivative: Permethylated (all available -OH groups methylated)
Temp. Limits: -10 °C to 200 °C (isothermal) or 220 °C (programmed)

Incorporates a phase consisting of a 2,3,6-tri-O-methyl derivative of β-cyclodextrin. This phase exhibits broad chiral selectivity and is good for terpenes and tertiary amines.

The permethylated beta-cyclodextrin is a stationary phase that has indicated a potential to separate a wide variety of racemates. Many of those separations are better resolved on other CHIRALDEX phases based on lower retention, better selectivity and greater efficiency. What the PM does especially well are some hydrocarbons like terpenes, certain underivatized alcohols and diols and some analytes with polar groups like tertiary amines.

Features:

Broad chiral selectivity
Strong inclusion/size selectivity
Beta most selective of cyclodextrins

Mechanism Observations:

Inclusion a dominant mechanism
Highest temperature stability of CHIRALDEX phases along with the DM

Size Selectivity:

Some size selectivity is evident with the permethylated phase. The beta form will cover a broad range of molecule sizes.
