Shim-pack GIST C18-AQ
Excellent Retentivity of Highly Polar Compounds Shim-pack GIST C18-AQ achieves strong retention of
Bonded Phase
Octadecyl Groups 1.9 µm, 3 µm, 5 µm
hydrophilic highly polar compounds compared to general C18 columns, while maintaining high inertness and durability in highly or 100% aqueous mobile phases. Shim-pack GIST C18-AQ is also able to reduce the absorption of basic and acidic compounds and achieve superior peak shapes in the analysis of metal complexes.
