Drinking water may look clean, but what about the ions you cannot see? In this application, the ChroZen 2120 IC was used to simultaneously determine seven major anions—F⁻, Cl⁻, NO₂⁻, NO₃⁻, Br⁻, PO₄³⁻, and SO₄²⁻—in bottled water samples. It demonstrates a reliable and practical IC method for routine drinking water quality analysis.
