Metrohm Process Analytics turnkey solutions come with our application guarantee and excellent after sales support and service.
Online Phosphate
Phosphate concentration from waste water (effluent and influent) is very commonly measured by so called “molybdenum blue’ Method. Ammonium molybdate and potassium antimonyl tartrate react in acid medium with orthophosphate to form phosphomolybdic acid, which is reduced to intensely coloured molybdenum blue by ascorbic acid.
Our analysers features:
- Automatic filtration and service free filter cleaning with air back flow and acid cleaning
- Acid cleaning to prevent algae growth in the system
- No needs for calibration
- Very accurate measurements thanks to long light path in the cuvette
- Big tube’s where the sample flow to prevent any blockages
- Very low running costs
- IP65 or IP66, depends of the analyser model
- Possible dilution to reach higher phosphate values, normally measuring range 0 – 1 mg/L
- Multiple sample streams in one analyser
Total Phosphorous Compounds
Total phosphorous compounds are measured using thermal digestion to breakdown organic and inorganic phosphate compounds to orthophosphate under the influence of persulfate and sulfuric acid. After digestion added ammonium molybdate and potassium antimonyl tartrate react in acid medium with orthophosphate to form phosphomolybdic acid, which is reduced to intensely coloured molybdenum blue by ascorbic acid.
