The OMNIS Coulometer is a fully automated system for trace moisture analysis (10 µg to 10 mg) in liquids, solids, and gases using coulometric Karl Fischer titration, without requiring titer determination. It features a potentiometric measuring range of ±2400 mV with 1.56 µV resolution and ±0.5 mV accuracy between −2000 mV and +2000 mV. Iodine generation enables water determination with a titration speed of up to 2.24 mg H₂O/min and 0.1 µg H₂O resolution. Reproducibility is ±3 µg for 10 µg to 1000 µg H₂O and better than 0.3% above. A Pt1000 temperature sensor offers ±0.4 °C accuracy from −20.0 °C to +150.0 °C. Polarization current is adjustable from −200 µA to +200 µA in 0.5 µA steps. This variant does not include a magnetic stirrer and is intended for stand-alone use or integration into an OMNIS system with optional modules.
OMNIS Coulometer without magnetic stirrer for stand-alone operation or as the heart of an OMNIS titration system. The coulometer can be enhanced with additional titration, dosing or coulometer modules.
Coulometry is the ideal method for water content determination in the trace range (10 μg to 10 mg absolute water content) in liquids, solids and gases. In addition, coulometric Karl Fischer titration is an absolute method making titer determination unnecessary.
