This phase has protective butyl side chains that allow for superior peak shape and enhanced separation of basic compounds under neutral and acidic conditions.
Octyl silane groups bound to the silica surface with non-polar end capping offer moderate hydrophobic selectivity and virtually eliminate silanol interactions.
Nitrile groups bound to the silica surface offer a unique polar selectivity under reversed phase or normal phased conditions.
Amino groups bound to the silica surface serve as a weak anion exchanger and offer polar selectivity under reversed phase and normal phase conditions.
Pentaflourophenyl groups bound to silica surface for a unique aromatic selectivity due to highly electronegative fluorine atoms on the periphery of the phenyl ring ligand.
The silica surface is covered with cross-linked diol groups for polar selectivity under hydrophilic liquid chromatography conditions.
A polar embedded C18 phase that offers balanced polar and hydrophobic selectivity. Enhanced polar retention under organic conditions. Low MS bleed. 100 % aqueous stable.
A polar endcapped C18 phase that provides extreme hydrophobic and slight polar selectivity. Extreme retention of hydrophobic compounds. Slight polar selectivity. Stable in 100 % aqueous mobile phase.
Densly bonded C12 phase providing an alternative hydrophobic selectivity to traditional C18 columns. Hydrophobic retention similar to a C18 with improved results. Sharper peaks for basic and tailing compounds.
A polar endcapped, ether-linked phenyl phase providing polar and aromatic reversed phase selectivity. Increased retention of highly polar and aromatic compounds. Highly reproducible and stable phenyl phase. Enhanced polar resolution in 100 % buffer mobile phases.
