Greater pH Stability(1.5-9.5)/
High Planar Selectivity

An excellent alternative to Wakosil-II HG or RS where greater pH stability (1.5-9.5) or aromatic shape selectivity is desired.

Wakosil-II AR (Click Here For Applications!) is obtained by bonding a trifunctional silane to Wakosil-II high purity silica, giving a higher carbon coverage (than HG or RS), yielding excellent reproducibility and higher chemical stability.

Features:

• High Reproducibility
• Ideal For Basic and Chelating Compounds (High Purity Silica)
• Ideal For Peptides and Aromatic Hydrocarbons
• High Planar Selectivity
• Uniform Spherical Surface
• Higher Chemical Stability (pH 1.5-9.5)
• Available For Both Analytical and Preparative HPLC
