High Temperature TOC COD BOD Online Water Analysis

Measuring TRUE Water Quality Continuously 

High Temperature Method for Reliable Online Water Analysis

Our LAR™ water quality analyzers use a high temperature method of 1,200°C, can completely oxidize a sample to accurately determine sum parameters – particularly when measuring the TRUE TOC with differing of concentrations.  LAR is your solution for the determination of parameters such as TOC, TNb, TOD, COD, BOD and toxicity.   We are the only company worldwide that, using a high temperature method of 1,200°C, can completely oxidize a sample to accurately determine sum parameters. Particularly when measuring the TRUE TOC with differing of concentrations.  

For an exact TOC measurement, all carbon bonds must be reliably combusted. Using a temperature of 1,200°C, we have developed a high temperature method which makes this possible! This temperature was chosen due to the proven fact that a complete oxidation of a sample cannot occur at temperatures below it. For example, the carbon bonds of carbonates only break fully when reaching a combustion temperature of 1,200°C. Basically, the lower temperatures deliver less exact measurement results. For this reason, we describe this as TRUE TOC.  Because of our high temperature capability, our analyzers do not require any catalysts. Catalysts are only necessary for the low temperature catalystic “high temperature” oxidation (680 – 1,100°C) to support the oxidization of the carbon bonds. However, the performance of the catalysts is lowered over time. This affects the measurement, necessitates continual new calibration, and eventually requires that the catalysts be replaced.

For special applications, we have a small number of mobile water analysis systems which can be used locally or abroad. Nothing else is needed except power supply, parking space and access to the sample stream or the liquid to be sampled.

  • Short-term rentals
  • Mobile measurements for the preparation of investment decisions, comparative measurements
  • Demonstrations of different analyzers
  • Life-demonstration and training on instruments under consideration of hygiene requirements

This century is characterized by global environmental challenges. Surface water and river water pollution is of special importance, as clean water forms the foundation of life. It therefore requires special attention in terms of quality. Regional authorities are requested to prepare measures for the improvement of water quality and to establish its provision. In order to secure sustainability in international projects, local authorities develop innovative solutions for the safety of water in cooperation with foreign companies and institutions. Lately, a variety of such joint projects are being realized around the world, with the German Federal Ministry of Education and Research especially sponsoring projects that are based on the cooperative partnership between industry and science. We at take our product responsibility seriously. For this reason, we make a continuous contribution to the development of innovative and environmentally friendly technologies.



Development of a furnace for water analysis with a reactor temperature of 1200°C and a power consumption of less than 230 W



The continued strong economic growth in Vietnam increases the demand on appropriate sites for industrial parks. Currently, there are more than 200 industrial zones (IZ) registered, the majority of which do not have sustainable wastewater treatment.
