Determining the chemical oxygen demand within minutes.

COD measurement is accomplished in about 3 minutes. Thus, 3 replication measurements per sample can be determined within less than 10 minutes.

The COD analyzer QuickCODlab offers enormous time and cost savings in comparison to standard procedures.

O2 detection. Simple and reliable.

An O2 detector determines the oxygen used to digest all the constituents. The determination of the oxygen demand is performed over a wide variety of measurement ranges. The QuickCODlab also reliably measures the real COD in relevant measurement ranges from 5 to 100 mg/l.

Very high salt concentrations. No problem.

The QuickCODlab easily masters salt concentrations of up to 10 g/l, and even up to 300 g/l of sodium chloride (NaCl) with the additional high salt option. The salts move through the oven and are carried out of the system together with the condensate finally being collected as solids in a special retaining device. This means that no salt residues can form in the oven and the sample does not have to be diluted, even at the highest of salt concentrations. This, in turn, having a positive effect on the accuracy of the measurements.
