Separation of chloride and bromide using Shodex IC SI-35 4D 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.

Shodex IC SI-35 4D with XAMS suppressor

Ion chromatography of anions on a Shodex IC SI-35 4D column (150×4 mm) using an eluent containing 3.6 mM Na₂CO₃ in water pumped at 0.6 mL/min at 45 °C. Background reduced to ~15 µS/cm by XAMS suppressor with ASUREX-A100 automatic regenerator. A Waters ACQUITY Arc system with modules QSM-R and FTN-R were used together with a Waters 432 conductivity detector. Injection of 20 µL of Cl¯ (5 mg/L), Br¯ (10 mg/L) in water.

Diduco is a leading provider of professional services in high performance liquid chromatography and manufacturer of the Xenoic® XAMS chemical suppressor and ASUREX automatic regenerator for ion chromatography.
