catalyst-free thermal oxidation method

Our catalyst-free thermal oxidation method is a valuable tool for water quality monitoring and measuring total organic carbon (TOC). This method involves the combustion of organic compounds in water through high-temperature oxidation, without the need for a catalyst.  Here’s how the catalyst-free thermal oxidation method works and its significance for water quality monitoring and TOC measurement:

  • Principle of Operation: In this method, a water sample is subjected to high temperatures (typically around 680-720 degrees Celsius) in a controlled environment. The organic compounds present in the water are oxidized to carbon dioxide (CO2) and water vapor.
  • Combustion Process: The combustion of organic compounds occurs due to the high temperatures, which break down the molecular bonds and convert the carbon-containing compounds into CO2. The combustion process is highly efficient and can achieve complete oxidation of organic compounds, resulting in accurate measurements of TOC.
  • Measurement of CO2: The CO2 produced during the oxidation process is measured using various techniques, such as infrared detection or gas chromatography. These techniques provide quantitative measurements of the CO2 concentration, which is directly proportional to the amount of organic carbon initially present in the water sample.
  • Advantages of Catalyst-Free Method: The catalyst-free thermal oxidation method offers several advantages for water quality monitoring and TOC measurement:
  • Speed and Simplicity: This method is relatively fast and straightforward compared to other techniques. It does not require the addition of any catalyst, reducing the complexity and cost of the analysis.
  • Wide Applicability: The catalyst-free thermal oxidation method can be applied to a broad range of organic compounds present in water, including both volatile and non-volatile substances. It offers excellent versatility for comprehensive water quality analysis.
  • High Accuracy: The combustion process in this method is highly efficient and achieves complete oxidation of organic compounds. This results in accurate measurements of TOC with high precision and reliability.
  • Sensitivity: The method is sensitive enough to detect low concentrations of organic carbon in water samples. It can detect organic contaminants, such as pesticides, pharmaceuticals, and industrial pollutants, which are of concern in water quality monitoring.
  • Compatibility: The catalyst-free thermal oxidation method can be easily coupled with other analytical techniques, such as UV spectroscopy or liquid chromatography, to provide complementary information on water quality parameters.

  • Compliance: The National Pollutant Discharge Elimination System (NPDES) program in the United States and other similar regulations in Europe require facilities that discharge wastewater to comply with specific pollutant limits and other requirements. Our LAR TOC water analyzer can help manufacturers ensure compliance with these regulations by monitoring the levels of total organic carbon (TOC) in their wastewater.
  • Process Control: Our LAR TOC water analyzer can also be used for process control purposes. By measuring the TOC levels in real-time, manufacturers can adjust their wastewater treatment processes to optimize efficiency and reduce costs.
  • Product Quality: In some manufacturing processes, high levels of TOC in the water can negatively affect the quality of the final product. The LAR TOC water analyzer can help manufacturers monitor and control the TOC levels in their process water to ensure consistent product quality.
  • Environmental Stewardship: Many manufacturers are increasingly focused on sustainability and reducing their environmental impact. By monitoring and controlling TOC levels in their wastewater, they can reduce their overall environmental footprint and demonstrate their commitment to environmental stewardship.

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.
