Unique design retains highly polar, water soluble compounds. Deactivated for both acids and bases. More stable in highly aqueous mobile phase. Stable and reproducible in the silica range of pH 2.5-7. Pyridine and phenol are separated with excellent peak shape.
Unique design retains highly polar, water soluble compounds.
Deactivated for both acids and bases. More stable in highly aqueous mobile phase. Stable and reproducible in the silica range of pH 2.0-7. The C18 chains remain extended for maximum retention stability even in pure aqueous mobile phases, and gradients can be employed from zero percent organic without concern about poor reproducibility or symmetry for early peaks.
