Mission: "We provide the most reliable online measurements to ascertain heavy metals in water with our cutting edge Analysers, Reagents, Consumables and Services."

SEIBOLD Wasser researches, designs and develops products and services for continuous quantitative analysis of heavy metals in water.
Because of the regular frequent online analysis you will get connected concentration data points. This data basis can be used for deep analysis of processes and trends.

To design good products and services you must not only know what the needs of your clients are today but also what they should have in mind tomorrow. There are some trends helping to predict the future needs. In general; environmental costs(1) will increase and the need for automation and stable processes will still drive businesses for the next centuries and people will have more worries about their families health and their drinking water.

Building Blocks.

On-Line Measurements Mission Critical Application
  • Learn more; know more. To stabilise and optimise processes.
  • To prove emissions to local authorities.
  • Monitoring to understand situations and trends.
  • Analyser up-time is the most important feature.
  • Automatic indication of measurement quality.
  • High accuracy in changing sample matrices.

Cyanide measurement principle.
Cyanide Principle
Cyanide measurement principle

SEIBOLD COMPOSER for Cyanide measures from very low to very high measurement ranges because of controlling independently the cycle speed for acid, base and air.
The measurement technology embedded is photometric (measurement of absorbance by adding reagents) and ISE (ion selective electrode, specific ions are separated by a membrane and measure by electrochemical principles).

Intelligent Photometer for multiple wavelengths.

Intelligent Photometer
Intelligent Photometer

  • Drinking water colour, turbidity and process water heavy metals in high ppm range.
  • High range direct heavy metals measurements.
  • Signal In: External Start. Command/Mode 2 bit. Led On, Zero, Extinction, Absorption.
  • Signal Out: 4-20mA, 2 Relays for pumps (i.e. sample, cleaning and valves, 1 Alarm/Warning Relay.

The Intelligent Photometer is based on a new controller platform following our new three phase electronic concept(4). The electronic board and software was developed by SEIBOLD Wasser to ensure perfect fit to our controller platform strategy. The intelligent Photometer has a robust controller embedded and communicates to a high resolution colour touch screen.
Signal in and out via relays to pumps and valves and 4-20mA for extinction/absorption indication.
The Intelligent Photometer can work in absorption mode and in extinction mode against zero. The pumps can function as stepper motor pumps and controlled via PWM.

  • Measurements based on Ion-Selective Electrodes are inexpensive and have an extremely wide concentration range.
  • ISE are very robust and durable and ideal for use in on-line measurement analysers.
  • Interfering ions, pH levels, or high concentrations are handled by specialised experimental methods and special reagents.
  • ISE are unaffected by sample colour or turbidity.
  • ISE can be used in aqueous solutions over a wide temperature range; typically in the range 0°C to 80°C.

ISE are available for the following ions: Ammonium NH4+ (NH3), Barium Ba++, Bromide Br -, Cadmium Cd2+, Calcium Ca2+, Chloride Cl-, Copper Cu2+, Cyanide CN-, Fluoride F-, Iodide I-, Lead Pb2+, Mercury Hg2+, Nitrate NO3-, Nitrite NO2-, Perchlorate ClO4-, Potassium K+, Silver Ag+, Sodium Na+, Sulphide S2-, Thiocyanate SCN-. All SEIBOLD COMPOSER for ISE can measure adopting standard addition and multiple standard addition practices.

(1) The need for clean water and the costs of pollution will increase dramatically: Source: WBCSD.
(2) Connecting the dots. Complexity drives measurement technology used in on-line and process analysers. WHO Drinking Water Guidelines, Table 8.4.
(3) The SEIBOLD Wasser TCM is about Total Costs of Measurements including direct costs for analyser and operation as well as indirect costs for downtime and risk.
(4) The electronic platform has to follow the requirements and the technology trends. Competitors analysers are either based on PC platforms with low operational stability (even on Unix variants) or PLC platforms with high stability but low technology use. Sensors and actors are the first layer and have to use new technology and a basic communication concept. The controller platform must be very stable and simple like a washing machine. Very simple electronics and processors and low code operating system. The third electronic platform is visualisation and communication. High technology to ensure functionality as all know to use and all kind of communication to central systems and mobile platforms.
