Ion Chromatography (IC)

Ion Chromatography (IC Analysis) Testing Technique

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.



IC - At a Glance

  • Information: Quantified concentrations & identification of unknown compounds
  • Sample Size: 500ml for gases, 500ml for liquids and 10g for solids
  • Detection Limits: Approximately 5mg/kg for solids, 1ug/L for liquids and 1mg/m3
  • Data Output: Concentration values and chromatograms on enquiry
