Key facts

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
