Dionex ICS-3000 Integrion HP Ion Chromatograph

Equipment full name: Dionex ICS-3000 Ion Chromatograph

Description: 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.

Sample submission: Water samples may be submitted to the water quality laboratory chemist for analysis.

Training: Student researchers and faculty who may be interested in training on how to operate the instrument and interpret the data, please contact the water quality laboratory to schedule training and time on the instrument. While the number of training hours may vary, depending on the student's knowledge and analytical skills, we require a minimum of four training hours prior to allowing the student to independently operate the instrument.
