Separation of seven inorganic anions using ICSep AN2 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.

ICSep AN2 with XAMS suppressor

Ion chromatography of anions on a ICSep AN2 column (250×4.6 mm) using an eluent containing 1 mM Na₂CO₃ and 3.5 mM NaHCO₃ in water pumped at 1.0 mL/min at 24 °C. Background reduced to ~13 µS/cm by XAMS suppressor with ASUREX-A200 automatic regenerator. Eluent pumping and conductivity detection by Metrohm 761 Compact IC. Injection of 20 µL of F¯(2 mg/L), Cl¯ (3 mg/L), NO₂¯ (5 mg/L), Br¯, NO₃¯ (10 mg/L), PO₄²¯ (20 mg/L), SO₄²¯ (15 mg/L) in water.
