THERMO SCIENTIFIC (DIONEX) Ion Chromatography Systems: Detection and quantification of ionic tracers (anions: bromide, chloride, iodide; cation: lithium) in waters; determination of the ionic composition of waters and solutions, etc.



CI ICS1100


ICS900 for anions with RFC30  automatic eluent generator and AS-DV autosampler.
ICS1100 for cations with AS-DV autosampler. 

Detection limits of the ion chromatography systems: Br-, Cl- : 1 µg/L ; I- : 50 µg/L* ; Li+ : 20 µg/L. Actual detection limits depending on natural concentrations in samples: Contact us for more information.

* Iodide can also be analyzed by molecular absorption spectrophotometry (see below). Detection limit: 5 µg/L.
