MACHEREY-NAGEL 723370.25 HYDRODEX ß-PM Special Capillary Columns for GC, Length: 25 m, 0.25 mm ID
Special Features
- Base material: cyclic oligosaccharides consisting of seven (β-cyclodextrin) or eight (γ-cyclodextrin) glucose units bonded through α-1, 4-linkages
- Regioselective derivatization of the hydroxyl groups leads to phases with varying enantioselectivity, which are well suited for GC enantiomer analyses
- Due to the high melting point of the HYDRODEX phases they are diluted with polysiloxanes
- Important advantage of cyclodextrin phases: many compounds can be analyzed without derivatization
