Descrição

Descrição geral

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.

Containing permethylated α-cyclodextrin embedded in an intermediate polarity stationary phase, Supelco α-DEX 120 columns provide unique selectivity for enantiomeric separations of small molecules. They are also recommended for separating positional isomers (phenols, xylenes, etc.).

Aplicação

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.
