Designed for aqueous and low pH mobile phases, Thermo Scientific™ Hypersil™ SAX LC Columns are highly stable silica-based quarternary amine strong anion exchange columns.
Use a glass column for applications where high inertness is required, such as for the analysis of active analytes. All glass columns undergo a proprietary high temperature silanization to ensure inertness.
Ascentis™ Express PCS-Phenyl-Hexyl columns are specifically engineered to provide efficient separation of basic, acidic, or neutral compounds under low ionic strength (formic acid) mobile phase conditions.
An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.
The bare silica stationary phase of Ascentis™ Express 5 μm HILIC provides a column that can be used for traditional normal phase separations using non-polar, totally organic mobile phases or for aqueous normal phase chromatography with the typical reversed-phase mobile phases for hydrophilic interactive liquid chromatography (HILIC) of basic, acidic, or neutral compounds.
