For the continuous online determination of the total organic carbon (TOC) in ultra pure water applications. Measuring range 0.1 to 1,000 ppb TOC
LAR’s toxicity analyzer NitriTox™ continually monitors water treatment plants for pollutants. Potential toxins in water are determined through the reaction of highly sensitive bacteria.
LAR’s QuickTONultra continually monitors the TNb content of water. Optionally, further sum parameters can be detected, too. At 1,200 °C, samples are completely oxidised and only within 3 minutes the TNb result is determined.
