Dionex offers a complete line of IC and RFIC columns for use with hydroxide and carbonate eluents. The IonPac polymeric columns address a variety of chromatographic separation modes including ion exchange, ion exclusion, and reversed-phase ion pairing and ion suppression. Our unique column chemistries are designed to solve specific applications. We offer a variety of selectivities and capacities for simple and complex sample matrices. Ion exchange and ion exclusion separations can be used to determine a variety of analytes including inorganic anions, oxyhalides, organic acids, oxyanions, cations, amines, and transition metals.

Chromatographic separations require appropriate HPLC columns for the specific application.  The Dionex Acclaim columns are available packed with reversed-phase, polar embedded phases, as well as specialty phases; and columns optimized for Rapid Separation Liquid Chromatography. Biological separations require unique packing material to achieve high resolution analysis of these compounds.

Biological separations often require unique chemistry to provide high resolution, high efficiency separations.  Dionex offers a variety of columns for proteins, peptides, carbohydrates, nucleic acids and more.

Dionex offers a wide range of accessories and suppressors for use with HPLC, IC and RFIC systems. The Dionex suppressor range decreases background conductivity of the eluent while simultaneously increasing the analyte response. Eluent generator cartridges are used for the electrolytic production of high-purity eluents for both isocratic and gradient analyses. The CRD removes carbon dioxide from the sample for improved recoveries of certain analytes. The OnGuard II cartridges remove matrix interferences from samples encountered in many IC applications. And to make your chromatography easy, Dionex has developed a range of concentrates and standards.
