Description

Description générale

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.

Les colonnes alpha-DEX 120 offrent une sélectivité unique pour la séparation des énantiomères de petites molécules ; elles sont également conseillées pour la séparation des isomères de position (phénols, xylènes, etc.).

Application

α-DEX^™ 120 was used in a GC column, in an experiment conducted to study the addition of catalytic enantioselective diethylzinc to a-substituted aldehyde, in presence of enantiopure ligand. It was also used to pack chiral column durin GC analysis, in an experiment to investigate lipase-mediated desymmetrization of glycerol with aliphatic and aromatic anhydrides.
