Hardness, ammonium and cooling-water chemistry all come down to the same six cations: Li+, Na+, NH4+, K+, Mg2+ and Ca2+. This chromatograph separates them in one run on methanesulfonic acid eluent, with suppressed or non-suppressed conductivity detection. Linearity holds at R² ≥ 0.999 over 0.1–50 mg/L, and detection limits are 5–50 µg/L.
