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.
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.
