Benefit from more than 2,200 state-of-the-art applications, conducted with the most accurate and efficient lab technology.
Water (surface, sea, etc.)
Accurate analysers are required to test water samples with high salinity or organic load
71% of our planet is covered by water. But all water is not equal, and analysing different water types offers different challenges in the form of sample preparation and/or matrix interferences.
Measuring critical contaminants in water requires analysers capable of measuring low concentrations. However, they must also be capable of handling samples with high organic loads or high salinity.
Metrohm provides high-quality analytical instruments, extensive application knowledge, and excellent service to support the analysis of your water samples.
