Standard Test Method for Anions in High Ionic Water by Ion Chromatography using Tandem Suppressed Conductivity and UV Detection

Importancia y uso:

5.1 Ion chromatography provides for both qualitative and quantitative determination of common anions, F ⁻, NO₂⁻, hydrogen phosphate ion (HPO₄^–2), Br ⁻, NO₃^–, and SO₄^–2, in the milligram per litre range from a single analytical operation requiring only a few millilitres of sample for analysis.

5.2 Anion combinations such as chloride/bromide (Cl ⁻ /Br ⁻) and nitrite/nitrate (NO₂⁻ /NO₃^–), which may be difficult to distinguish by other analytical methods, are readily separated by ion chromatography.
