Descripción

Descripción general

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.

Estas columnas proporcionan una selectividad única para separaciones enantioméricas de moléculas pequeñas; también recomendada para separar isómeros posicionales (fenoles, xileno, etc)

Aplicación

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.
