Separation of seven inorganic anions using IonPac AS4A-SC column

Separation of inorganic anion standards at eluent conditions recommended by the column manufacturer.

Background and noise was suppressed by Xenoic® XAMS membrane suppressor with the Xenoic® ASUREX automatic regenerator.

IonPac AS4A-SC with XAMS suppressor

Ion chromatography of anions on a IonPac AS4A-SC column (250×4 mm) using an eluent containing 1.8 mM Na₂CO₃ and 1.7 mM NaHCO₃ in water pumped at 2.0 mL/min at 24 °C. Background reduced to ~13 µS/cm by XAMS suppressor with ASUREX-A100 automatic regenerator. Eluent pumping and conductivity detection by Metrohm 761 Compact IC. Injection of 20 µL of F¯, Cl¯ (2 mg/L), NO₂¯ (5 mg/L), Br¯, NO₃¯ (10 mg/L), HPO₄²¯, SO₄²¯ (15 mg/L) in water.
