Description
General description
Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.[1]
The chiral stationary phase in β-DEX 120 columns contains permethylated β-cyclodextrin embedded in an intermediate polarity stationary phase. They are recommended for the enantiomeric separation of a wide range of chiral compounds (ketones, esters, alkanes, alkenes, alcohols, acids, ethers, etc.). The 10% (β-DEX 110) and 20% (β-DEX 120) β-cyclodextrin content alters the elution order while maintaining similar enantioselectivity.
Application
β -DEX™ 120 chiral capillary column was used for the GC analysis of chiral Bis(oxazolinylmethyl)amine ligand.[1]
