Ion Chromatography (IC Analysis)

Ion Chromatography (IC) is an analytical technique that separates ions and polar molecules based on their charge, and is closely related to high-performance liquid chromatography (HPLC).

Each species interacts slightly differently with the stationary phase (a resin-filled column), and thus has a different retention time. Once separated, each species can then be quantified individually as it leaves the system.

  • Highly selective
  • Low limits of detection, with a wide analytical range
  • Analysis of halides, anions and elements not available by ICP or XRF
  • Analysis of molecular species rather than elements
  • Reproducible.

Typical Applications

  • Trace analysis of environmental soil and water samples
  • Total halides (F, Cl, Br) from pyrohydrolysis extraction
  • Trace analysis of any material that can be digested into an aqueous matrix
  • Drinking water analysis for contamination.

Typical Industries using Ion Chromatography

  • Environmental testing
  • Food and drinks
  • Materials
  • Minerals
  • Glass, ceramics and refractories
  • Healthcare.
