Determination of the chemical oxygen demand (COD) using a sample changer
The chemical oxygen demand (COD) provides information about all the organic constituents that can be oxidized by potassium dichromate.
The COD determination has increased in importance in recent times as it is used in several countries for calculating the wastewater charges.
Max. 16 samples can be titrated fully automatically with the 676 Sample Changer. After the titration the used solution is aspirated off into a waste container using a 683 Diaphragm Pump and the sample vessels are rinsed.
