Beschreibung

Allgemeine Beschreibung

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.

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.

Anwendung

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.
