Heavy Metals Detection
Seibold Wasser heavy metal detection systems are designed for continuous quantitative analysis of heavy metals in water. The continuous online analysis produces connected concentration data points that can be used for deep analysis of processes and trends.
Water Quality Assurance
Seibold Wasser heavy metal detection systems are ideal for quality assurance, monitoring emission limit values and process stabilisation. They are automated and the frequency of the measurements is determined by the process flow and typically ranges from 30 minutes to 2 hours. Robustness, ease of operation and maintenance are key features of the design.
The colorimetric analysis heavy metal detection method, endorsed by the World Health Organization, is reliable and accurate with a low total cost of measurement. Seibold Wasser systems are suitable for diverse applications such as monitoring heavy metal concentrations in drinking water and industrial waste water, and measurement of cyanide in coke production. Seibold Wasser systems are used widely from monitoring river water in Kathmandu to measuring the lead content of water from the reconstruction of the Notre Dame cathedral.

Applications
Drinking Water
In almost all cases raw water must be treated to produce high quality drinking water. These treatment steps eliminate heavy metals, organic matter and turbidity and colour. To ensure high quality of drinking water and to control the process, on-line measurements are mandatory.
- Analyser up-time is critical
- Complex sample matrix
- Non toxic reagents, non toxic waste
Industrial Waste Water
To monitor emission levels and to control process quality on-line measurements are key to industrial clients.
Changing sample matrix needs special measurement strategies and in some cases adaptation of reagents.
- Turbidity and colour of sample must be compensated
- Cleaning of measurement cell
- Very robust and reliable also under unfriendly conditions
Cyanide Measurement in Coke Production
During processing coal Cyanide can be a side product and must be measured to control treatment steps. The concentration is measured continuously by ISE or photometric analysers.
- Dirty
- Must handle long unobserved operation; very robust and reliable
- Complex sample matrix
- Large measurement range must be handled
River Water Monitoring
Riachuelo in Buenos Aires is one of the most contaminated rivers. Argentina Government started an initiative cleaning this river. The first step was to size the problem and measure the most dangerous inorganic matter. Continuous measurements of Chromium should help to understand and size the problem of pollution.
- Measurement of CrIII and CrVI in one measurement step
- Low measurement range starting at 1ppb
- Handle turbidity and particles without filtration
- Unknown and changing sample matrix
