A Nature publication from 07 April 2021 highlighted a core challenge in water analytics:
while colorimetric methods are powerful and widely used, online measurements often suffer from interferences, matrix effects, and long-term instability when transferred from the lab into real-world operation. https://www.nature.com/articles/d41586-021-00930-2
These limitations are not theoretical — they are exactly what operators experience in continuous water monitoring:
drifting signals, false positives, reduced detection confidence, and limited validation of results.
How Seibold Wasser turns research into reliability
At Seibold Wasser, we took these findings as a starting point — not a limitation.
By rethinking online analyser design from first principles, we addressed the weaknesses described in the literature and translated scientific insight into robust field solutions.
Our approach focuses on four key advances:
• Design before complexity
Using flow injection analysis, kinetic measurement, and photo-spectral evaluation, we reduce system complexity while increasing signal clarity. Fewer variables mean more stable measurements over time.
• Proven principles, demonstrated in practice
Our online analysers — including our arsenic systems — are fully equipped to demonstrate how controlled reaction conditions and kinetic evaluation significantly reduce matrix effects and interferences.
• Mobility without compromise
With our new mobile analyser, we enable short-term and validation measurements using the same design logic — bringing laboratory confidence directly to the field.
• Combining methods for higher certainty
Building on current research, we combine colorimetric and voltammetric measurement technologies in a single analytical concept.
This dual-principle approach:
-
increases resistance to interferences
-
extends detection limits
-
enables internal validation of results
-
improves long-term measurement confidence
Beyond measurement — toward trust
The key message of the 2021 Nature publication is clear: measurement quality defines decision quality.
At Seibold Wasser, we go one step further — transforming scientific understanding into online analysers that deliver reliable, verifiable results in real operating conditions.
Because in water monitoring, trust in data is everything.
