Ion Chromatography Systems

  • Automated eluent preparation using unique Reagent-Free Ion Chromatography-Eluent Generation (RFIC-EG) technology.
  • Single- and dual-channel system configuration options.
  • Finger-tight connections that minimize dead volume and make connections easier.
  • High-pressure ion chromatography (HPIC) allows the use of smaller particle size column packings which improves peak resolving power and shortens run times.
  • Electrolytic suppression.

IC and RFIC Column Categories

  • 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™ an CarboPac™ columns, enable direct analysis of amino acids and carbohydrates by ion chromatography (IC).


  • Hydroxide-Selective Anion-Exchange Columns: Use these high-capacity, high-resolution columns for inorganic anions, oxyhalides including bromate, organic acids, haloacetic acids, and multivalent anions in complex matrices.
  • Ion-Exclusion IC Columns: Ideal for separation of aliphatic organic acids and alcohols in complex samples, and for monitoring trace levels of borate in high-purity water.
  • Carbonate Eluent Anion-Exchange IC Columns: Perform well-characterized isocratic separations, including regulated methods for drinking and wastewater, using these carbonate eluent columns.
  • Amino Acid IC 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: Use these specialty columns for a variety of applications including transition metals, polyvalent anions, hexavalent chromium, sulfide, and cyanide.
  • Carbohydrate IC Columns: These columns have been optimized for high-resolution IC separation of mono-, di-, poly-, and oligosaccharides, and sugar alcohols.


  • Cation-Exchange IC Columns: Obtain high-resolution separations of inorganic cations, ammonium, and amines, including alkylamines, alkanolamines, and biogenic amines.
  • Reversed-Phase IC Columns: 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: 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.
  • IC Trap Columns: These columns trap eluent contaminants, preventing them from interfering with analytical results.
