ICON Analyser
Dedicated online photometer for water and wastewater analysis.
If there is one thing that everybody depends on, it is water. We drink it every day. We use it in nearly every industry as a cleaning agent, to moderate processes, or actually as a solvent in production. Once we have used the water, it is released back into the environment again. Therefore, it is of utmost importance to society to monitor water quality.
The ICON Analyser has been developed by Metrohm Process Analytics specifically for the near-continuous analysis of a large number of parameters critical for water quality.
ICON Analyser
Dedicated for the analysis of water and wastewater, and can be used in various situations:
- Wastewater effluent
- Surface water
- Drinking water
- Ultrapure water
- Steam and condensate water
- Ion-exchange systems
- Boiler feed water
- Demineralisers
Highlights
- Very easy to use: Just connect the power, sample, and reagent lines and the ICON Analyser is fully operational.
- Superior reliability: Validation, cleaning and calibration are standard features which significantly reduce downtime and operator intervention.
- Outstanding sensitivity & accuracy: Depending on the analyte and matrix, the determination ranges of the ICON Analyser vary from trace µg/L to mg/L.
- Secure: The electronics part is 100% seperated from the wet part of the analyser.
Colourimetric method. For more accuracy, the ICON Analyser measures twice during one analysis cycle:
The first measurement is from the raw sample as a reference, which compensates for the colour and turbidity of the sample and the fouling of the cell. The second measurement of the sample is taken after the addition of colour reagent and completion of the reaction. Based on the calibration and the differential absorbance, the software calculates the analyte concentration. The ICON Analyser can measure a variety of components in water. All applications have been field-tested and have an excellent analytical performance.
Flexible software for straightforward control
The ICON Analyser is equipped with a graphical user interface for easy access to your analyses and results. There are multiple user levels offered in the software which are suitable for any operator. With up to 30 programmable steps available for each analysis, the ICON offers more than enough flexibility to adjust to the needs of any user. Validation, cleaning, and calibration are standard features built in to the analyser which assist in the optimisation of the system and help ensure the most accurate results are obtained. A graphical overview of the most important data from your application is available at your fingertips.
Simplified layout for easy access
The ICON Analyser is complete, preconfigured and programmed for your specific application. Just connect the power, sample, and reagent lines and the easy-to-use analyser is fully operational. The high uptimes and minimal maintenance of the ICON Analyser lead to lower operating costs. The ICON Analyser as designed ensures the highest level of robustness in the electronics, mechanics, and hydraulics components.
• Dual compartment enclosure to ensure complete separation between the electronics and the wet part, therefore no leakages possible into the electronics part
• Built-in peristaltic pump for sampling
• Thermostated reaction cell
• Automatic validation and automatic cleaning
• 2 sample streams can be monitored
• Up to 3 reagents can be added – simply add a pump for additional reagents

Photometric determination of silica
Application fields: Cooling water, high-pressure boiler feed, high- purity water.
Silica is used in a variety of industries: from the production of wafers to glass and ceramics manufacturing and chemical production. In the water-steam cycle of power plants, silica is considered one of the major impurities, causing boiler scale and deposits on steam turbine blades. Impurities precipitated out of the water form deposits on heat transfer surfaces, which result in reduced boiler efficiency, overheating, and eventually outages. Silica also plays an important process control role at demineralisation plants where deionised water is produced. An increase in the silica concentration signals an exhausted ion-exchange bed and is therefore an indicator that regeneration is necessary.
Photometric determination of iron(II) and (III)
Application fields: Drinking water, surface water, industrial waste- water, cooling water, high-pressure boiler feed
Iron is quite abundant naturally in our environment; it is also used in many different applications and industries worldwide. Soluble Fe(II) is present in anaerobic water, oxidising to Fe(III) when exposed to air or other oxidising agents. The resulting turbidity from less-soluble Fe(III) can cause problems. In drinking water, an excessive presence of iron is a problem, as it affects both the taste and smell. There are many ways for iron in all forms to be introduced into our water sources, making it an important analyte to measure.
Photometric determination of phosphate
Application fields: Surface water, municipal waste, industrial waste- water, cooling water, high pressure boiler feed
Phosphorus compounds are essential to the growth of plant life and other organisms. However, the increasing concentrations of these compounds from wastewater and agricultural runoff create nutrient imbalances in lakes and other areas. This imbalance promotes an increase in algal blooms which can eventually lead to total oxygen depletion (anoxia), resulting in the death of fish and other aquatic animals. Phosphates can be introduced to the environment via agricultural (fertiliser) run-off resulting from rain storms or snow melt. Other wastewaters may also contain higher concentrations of phosphates, introduced by detergents and other cleaning solutions. Boiler water is frequently treated with phosphates to prevent boiler scaling leading to premature boiler failure.
Photometric determination of ammonia
Application fields: Cooling water, surface water, municipal waste- water, industrial wastewater
Ammonia can come from a variety of sources, with agriculture and wastewater treatment among the largest producers. Ammonia is used as a precursor to create many fertilisers. High concentrations of ammonia or ammonium salts are present (depending on the type of fertiliser in use) which contribute nitrogen to the environmental nutrient balance, promoting plant growth. Nitrogen is a limiting nutrient in marine environments, thus its increase due to agricultural runoff or from improperly treated wastewater can create significant ecological imbalances and anoxia, similar to the environmental effect of excess phosphates. Nitrification converts ammonium into nitrite and nitrate. Compounds are typically added to fertilisers to stop this process because nitrite and nitrate are much more water-soluble and contaminate water sources. Wastewater treatment uses both nitrification and denitrification processes to convert ammonium into harmless nitrogen gas, which is then released into the atmosphere.
