Separation of chloride, nitrate and sulfate using Hamilton PRP-X110 column

Ion chromatography of anions on a Hamilton PRP-X110 column (150×4.1 mm) using an eluent containing 1.8 mM Na₂CO₃ and 1.7 mM NaHCO₃ in water pumped at 0.8 mL/min at ambient temperature. Background reduced by XAMS suppressor with ASUREX-A100 automatic regenerator. Eluent pumping, injection and conductivity detection by Cecil Instruments IonQuest 2 system. Injection of 100 µL of about 0.2 mg/L of Cl¯, NO₃¯, SO₄²¯ in water.
