Analysis of Tap Water Using ICDS™-40A Suppressor Unit

The ion chromatograph is an outstanding instrument for high-sensitivity measurement of the ionic contents in solutions. Because of this feature, it is used in many fields, including the environment, chemicals, pharmaceuticals, and foods. In the field of tap water quality analysis, use of the ion chromatograph in measurements of multiple water quality standard items is specified in "Method Determined by the Minister of Health, Labour and Welfare on the Basis of the Ordinance Provisions Relating to Water Quality Standards" (Notification No. 261 issued by the MHLW in 2003, sequential revision).
This article introduces an example of anion analysis of tap water based on the above-mentioned Ministerial Notification using a Shimadzu ICDS-40A suppressor unit.
