The Dionex ICS-3000
Ion chromatography is used to determine anions and cations in a variety of liquid samples such as natural waters and synthetic solutions.
A selection of separation columns and detectors make this a versatile instrument for ion analysis using gradient or isocratic elution. Solid samples can be analysed after suitable sample preparation.
Examples
- common inorganic cations and anions in natural waters
- fluorine and chlorine in rocks and minerals
- organic and inorganic acids released by natural and synthetic materials
