IEE-WATERQUAL-Dionex ICS-3000 Ion Chromatography

The Ion Chromatograph is used in the water quality laboratory to measure concentrations of major anions, including bromide, chloride, fluoride, nitrate-N, nitrite-N, phosphorus-P and sulfate. The chromatographic process separates the different ions within the sample and the amount of anion is measured by the change in conductivity as the species passes through the detector. Samples require filtration using a 0.45µm filter and samples must be stored at 4ºC.

Analytical Method: Our laboratory follows Standard Methods for the Examination of Water and Wastewater, 23rd Edition. Bromide, chloride, fluoride, nitrate-N, nitrite-N, phosphorus-P and sulfate are analyzed following 4110B.
