QuickCODlab = a Clean COD measurement in the laboratory within minutes!

COD AT A GLANCE

  • The COD value indicates the amount of oxygen consumed during the oxidation of organic substances of a water sample.
  • Standard COD procedures are subject to criticism due to their high consumption of hazardous chemicals.
  • A reliable measurement system needs to be environmentally-friendly and free of chloride interference.
  • A temperature of 1,200°C guarantees complete combustion and eliminates the need for chemicals.
  • The QuickCODlab precisely determines the COD within minutes.

The COD procedure from LAR Process Analyzers AG is based on the thermal oxidation of the sample at 1200°C, with subsequent detection of the oxygen consumption. This method (ASTM D6238 – 98) has been employed hundreds of times in the field of online monitoring and has been specially developed for use in the laboratory.

The crucial point with QuickCODlab is the high-temperature procedure developed by LAR, which enables the reliable oxidization of all the organic compounds in the sample at a temperature of 1,200°C.  This procedure does not need any catalysts or other hazardous or corrosive reagents.  Furthermore, the measurement results are free of chloride interference due to the unique process management.  The homogenized sample is injected directly into the reactor, where it is completely oxidized and accurately analyzed with an O2 detector.

Fast. Clean. Precise

The QuickCODlab ensures a high operational reliability and is easy to use. The measured values are output directly to a standard computer and can be quickly and easily processed. The COD measurement is available in just a few minutes.
