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


Hydroxide-Selective Anion-Exchange Columns   Ion-Exclusion IC Columns   Carbonate Eluent Anion-Exchange IC Columns   Amino Acid IC Columns
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.
Specialty Anion Exchange IC Columns   Carbohydrate IC Columns   Cation-Exchange IC Columns   Reversed-Phase IC Columns
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.
  IC Concentrator Columns   IC Trap Columns  
  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.
