Aluminium analyser watertreatment station, coalfired electrical power plant Treated raw water has to be checked for Aluminium content to be sure there is no excess of a certain limit at 3 sampling spots. Analyses is based on a fotometric reaction and detection in a single beam fotometric unit against blankvalue. Range from 0.02 to 0.5ppm, measurement is done every 15 minutes.

Iso-Amyl/Nitrate analyser fertilizer industry Processfluid has to be checked for NO3 and Isoamylalcohol. Both values have to be as low as possible for environmental and cost reasons. Nitrate measurement is done by UV-spectroscopy without chemicals. Amylalcohol needs an extraction step with an organic phase and UVspectroscopy afterwards. Murtac developed an extraction unit fulfilling the labprocedure - doing extraction, washing, neutralisation and phase seperation perfectly. (Please do not hesitate to ask for the datasheet “Extraction unit” with more details.) Measurement ranges are 0-200ppm for Isoamylalcohol and 0-1500ppm for Nitrate. The Nitrate determination is fully compareable to lab measurement and matches entirely with the lab results. This applies to the Amylalcohol measurement also - fully compareable to lab-results (as exactly the same procedure ) with an even better accuracy. Extraction and phase seperation, fitting to several lab procedures, can be done by this extraction-unit, as an enlargement of the existing digestion and distillation procedures.

Hardnessanalyser ultralow range watertreatment station, electrical power and heating plant. Hardness of water in the treatmentstation has to be monitored at a very low level on several sampling spots - from the outlets of the iron exchangers until the ready made, stored make up water. Determination is done by titration using a copper electrode as a detecting element. Ultra precise determination with an excellent repeatability gives results below lab sensitivity. Measurement range from 5-100 MICRO VAL.
