further options available
Response time: 3 minutes
Determination of the real oxygen demand
Proven thermal temperature combustion
Reliable measurement without reagents
Excellent chloride acceptance
The COD analyzer is suitable for many types of water:
Industrial waste water
High salt concentrations
procedure is based on the thermal oxidation of the sample at 1,200°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 further for
use in the laboratory.
The high-temperature procedure developed by LAR enables the reliable
oxidization of all the organic compounds in the sample at a temperature
The procedure does not need any catalysts or other hazardous or corrosive reagents.
Furthermore, the measurement results are free of chloride interferences due to the unique process management.
The homogenized sample is injected directly into the reactor where it is
completely oxidised and accurately analysed with an O2 detector.
