The analysis of common anions in environmental water samples is among the most frequently-used applications of Dionex ion chromatographs in the past 25 years. The environmental testing industry makes broad use of ion exchange separation of fluoride, chloride, nitrate, sulfate, bromide, nitrate and phosphate by suppressed conductivity using EPA, ASTM and ISO methods. Of these methods, EPA Method 300.0 (Part A) and 300.1 (Part A) are among the most-referenced IC methods.
