GB/T 14642-2009 stipulates the use of Ion chromatography to determine various ions in industrial circulating chilled down water and boiler water. The standard describes the principle, clarifies the requirements of equipment and reagents. Detailed description of water sample collection, pretreatment steps, and Ion Chromatography operation process, including parameter setting, calibrated Linear dispersion drawing and sample determination. It can accurately determine the content of six ions such as fluorine, chlorine, and phosphoric acid root, providing a key basis for industrial water quality monitoring, helping enterprises ensure the safe operation of equipment, and promoting the standardization and standardization of industrial water testing.
