In a single run: automatic water quality analysis

In a single run: automatic water quality analysis

The determination of various physical and chemical parameters is necessary for evaluating water quality: electrical conductivity, pH value, p and m value (alkalinity), chloride content, calcium and magnesium hardness, total hardness and fluoride content. The Metrohm Application Bulletin 178/4 describes how to determine the above-mentioned parameters in a single analytical...

Boron in desalination water

Boron in desalination water

Boron, naturally present in seawater, is not something you want to be drinking a lot of. Intake per day is approximately 2 mg. For plants, boron levels are critical. Levels above 1 mg/L will destroy many crops including strawberries. Due to the toxic nature of high levels of boron, the...

Metrohm: Total nitrogen, total kjeldahl nitrogen, total phosphorus in water, wastewater as per ASTM D8001

Total nitrogen, total kjeldahl nitrogen, total phosphorus in water, wastewater as per ASTM D8001

Distillation vs Ion Chromatography Typical analysis of total nitrogen requires a distillation followed by colorimetric determination. As distillation is a tedious process and not reproducible, errors are easily introduced. ASTM D8001 provides a simple solution for simultaneous determination of total nitrogen and phosphorus using the robust Metrosep A Supp 16...

Metrohm Process Analytics: Online copper analysis to control Legionella in hot or cold water supply

Online copper analysis to control Legionella in hot or cold water supply

Copper-silver ionization Copper-silver ionization disperses positively charged copper and silver ions into the water system. The ions bond electrostatically with negative sites on bacterial cell walls and denature proteins. Over the long term, the presence of copper and silver ions destroy biofilms and slimes that can harbor Legionella, the bacteria...
