Analyzes of the concentration of major anions in solution

Dionex ICS 1000

Ionic Chromatography for anion concentrations analysis (F^-, Cl^-, NO₂^-, Br^-, NO₃^-, PO₄^3-, SO₄^2-)

Description of instrument:

Ionic chromatography (Dionex ICS 1000) measures the anion concentrations of solutions. The separation of anions can be done on different columns depending on the matrix and ions of interest.

Principle of analysis:

A liquid sample (filtered) is introduced, from the autosampler, into an injection loop, then through a column separating the ions which arrive, one after the other, separated by the column, on a detection cell (here conductimetry). The concentration of the anions is determined in relation to a previously established calibration range.

Analyzes carried out on the instrument:

Major anions (F^-, Cl^-, NO₂^-, Br^-, NO₃^-, PO₄^3-, SO₄^2-) between 0.05 and 100 ppm depending on the elements with an accuracy of +/- 5%, only on liquid solutions (filtered).
