SUPELCO Astec CHIRALDEX B-PM手性氣相色譜柱 毛細(xì)管柱
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:
Mechanism Observations:
Size Selectivity:
Some size selectivity is evident with the permethylated phase. The beta form will cover a broad range of molecule sizes.
