Macherey-Nagel™ LIPODEX™ E Capillary Columns for GC

Enables many compounds to be analyzed without derivatization. Macherey-Nagel™ LIPODEX™ E Capillary Columns for GC are phases with eight γ-cyclodextrin glucose units for enantiomer separation in gas chromatography. This lipophilic phase with long nonpolar ligants is a chemically non-bonded phase.

Description

A major advantage of LIPODEX columns are that many compounds can be analyzed without derivatization. However, for certain substances, enantioselectivity can be favorably influenced by formation of derivatives. Regioselective alkylation and/or acylation of the hydroxyl groups leads to lipophilic phases with varying enantioselectivity, which are well suited for GC enantiomer analyses.

It is not possible to make a general prediction about which LIPODEX™ phase could solve a given separation task. Even for compounds with small structural differences or within homologous series, the enantiodifferentiation can be quite different.
