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.
