Beschreibung

General description

α-DEX 120-Säulen ermöglichen eine einzigartige Selektivität bei der Enantiomerentrennung kleiner Moleküle. Sie werden ebenso für die Trennung von Positionsisomeren (Phenolen, Xylolen etc.) empfohlen.

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.

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.
