Macherey-Nagel™ LIPODEX™ C Capillary Columns for GC

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

Beschrijving

Beschrijving

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.

  • Base material: cyclic oligosaccharides consisting of seven β-cyclodextrin glucose units bonded through α-1,4-linkages
  • heptakis-(2,3,6-tri-O-pentyl)-β-cyclodextrin
  • Ligands: R2=R3=R6=pentyl; n=2
  • Recommended for alcohols, cyanhydrins, olefins, hydroxycarboxylic acid esters, alkyl halides
