GC Capillary columns LIPODEX® E
LIPODEX® cyclodextrin phase for enantiomer separation
base material: cyclic oligosaccharide consisting of eight glucose units bonded through α-1,4-linkages (y-cylodextrin) regioselective alkylation and acylation of the hydroxyl groups leads to a lipophilic phase, which is well suited for GC enantiomer analyses; important advantage: many compounds can be analysed without derivatisation (however, for certain substances enantioselectivity can be favourably influenced by formation of derivatives)...
