COD Analysis for Laboratories

LAR's QuickCODlab is a COD analyzer for the determination of the chemical oxygen demand (COD) in laboratory applications. Water samples will be injected via a precision syringe or via autosampler. Both injection systems are equipped with special syringes so that unfiltered water samples incl. particulates can easily be injected into the oven. Thus, operators do not need any sample preparation such as filtration. The COD analyzer works with a high temperature combustion method at 1200 °C. At this temperature all compounds are fully oxidized. As a result, no chemicals are needed and the measurement results are free of chloride interferences. The amount of oxygen needed is detected by an oxygen detector. The determination of the chemical oxygen demand takes place in less than 2 minutes.

In contrast to cuvette tests and potassium dichromate method, the environmental friendly high temperature method used is characterized by a high operational safety.
