Ion Chromatography

Working principle / output

Ion Chromatography (IC) or ion-exchange chromatography is a technique that separates ions and polar molecules in liquids according to their affinity with an ion exchange resin. The ions are selectively attached to the resin of the chromatographic column from where they are then gradually removed according to their size, charge and degree of hydration. Each ionic species is thus separated and detected by conductivity at the exit of the column.

Key features

  • Model: Thermo Scientific Dionex ICS-5000+
  • Determination of ions (anions and cations) contained in liquids
  • Analysis of organic acids and inorganic anions in complex matrices
  • Detection limit: up to 0.1 ppm (mg/L)
  • Dual pump system, conductivity detector and temperature-controlled room
  • RFIC (reagent-free IC) eluent generation to produce high-purity potassium hydroxide and methanesulfonic acid (MSA) eluents electrolytical
  • Automatic sample changer for 50 samples
