The raw water sample is oxidized at 1,200 °C and the CO2 produced is deteced and quantitatively determined. High Temperature Method at 1,200 °C
LAR’s COD analyzer QuickCODultra™ is the most reliable measurement system for the roughest wastewater applications. Due to an unrivaled injection and oxidation technique, the QuickCODultra easily handles sticky, fatty, salty, and high-particle samples unlike other COD analyzers without the need of any hazardous chemicals.

LAR’s toxicity analyzer ToxAlarm™ continually monitors drinking and surface water 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.
