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.
