In early 2025, an extended field test of the SEIBOLD Wasser Online Analyser was conducted for Uranium at a Wismut site.
A key aspect of the evaluation was the correlation of the analyser’s measurement results with laboratory reference data.
If discrepancies arose, we adjusted the measurement procedure and optimised the colourimetric reagents to ensure accuracy.
The outcome of this validation phase demonstrated a perfect alignment between the uranium concentrations measured by the SEIBOLD Wasser analyser and those obtained from simultaneous laboratory analyses — confirming both the reliability and precision of the technology.
Seibold measures online, where others can’t.
