Ion Chromatography Columns
Unique column chemistries designed to solve your application challenges
You’ll find a complete line of Thermo Scientific™ Dionex™ IonPac™ columns for hydroxide, carbonate, and methanesulfonic acid (MSA) eluents. Many are now available with our newest innovative format—capillary and 4µm particle size. Our BioIC columns, the Thermo Scientific™ Dionex™ AminoPac™ and CarboPac™ columns, enable direct analysis of amino acids and carbohydrates by ion chromatography (IC).
IC and RFIC column categories
Use these high-capacity, high-resolution columns for inorganic anions, oxyhalides including bromate, organic acids, haloacetic acids, and multivalent anions in complex matrices.
Ideal for separation of aliphatic organic acids and alcohols in complex samples, and for monitoring trace levels of borate in high-purity water.
Perform well-characterized isocratic separations, including regulated methods for drinking and wastewater, using these carbonate eluent columns.
Obtain high-resolution separations of free amino acids without derivatization, of phosphorylated amino acids, and of common oxidation products of sulfur containing amino acids.
Use these specialty columns for a variety of applications including transition metals, polyvalent anions, hexavalent chromium, sulfide, and cyanide.
These columns have been optimized for high-resolution IC separation of mono-, di-, poly-, and oligosaccharides, and sugar alcohols.
Obtain high-resolution separations of inorganic cations, ammonium, and amines, including alkylamines, alkanolamines, and biogenic amines.
Use these columns for ionizable compounds (e.g., surfactants) or for traditional reversed phase applications. Use mixed-mode columns for hydrophobic, neutral and ionic species.
Designed primarily for high purity water analysis, these columns retain the ions of interest while eliminating the matrix interferences, thus concentrating the analyte and lowering detection limits.
These columns trap eluent contaminants, preventing them from interfering with analytical results.
Dionex IonPac columns are IonPac polymeric columns for use with hydroxide, carbonate, and methanesulfonic acid eluents. Eluents can be delivered by Reagent-Free™ Ion Chromatography (RFIC™) systems using eluent generation cartridges. Dionex IonPac columns address chromatographic separation modes including ion exchange, ion exclusion, reversed phase ion pairing, and ion suppression.
- A variety of selectivities and capacities accommodate 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
- Many Dionex IonPac columns are now available in capillary format
- New 4µm resin technology offers highest efficiency and improved resolution
Dionex offers a variety of columns for the high resolution, high efficiency analysis of biological molecules such as amino acids and carbohydrates, separation of which by IC often involves unique column chemistries.
