Technique: ion chromatography
Typical cationic analytes: Li+, Na+, NH4+, K+, Mg2+, Ca2+
Typical anionic analytes: F- , Cl-, NO2-, Br-, NO3-, SO42-, PO43-, acetate, formate, oxalate
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.
- 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
