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.

With the VisoTurb® 700 IQ WTW presents a family of optical sensors for turbidity and suspended solids measurement.
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.
Our new QuickTOCuv II is state of the art and has more great features. LAR’s TOC analyzer QuickTOCuv II is ideal for fast and reliable online monitoring in pure, drinking, surface and wastewater.
LAR’s QuickTOCultra continually checks the TOC content of waste water. Optionally, other sum parameters can be detected aswell. At 1,200 °C,msamples are completely oxidised and within 3 minutes the TRUE TOC result is determined.
