AUTOMATIC ANALYZER OF COD "EXPERT-001-COD"
On the basis of the main unit of EXPERT-001
The registration number in the National standard Commitees of Russia and Ukraine 21068
|
The instrument aims at the express-measurement (2-8 min) of the mass concentration of oxygen, consumed during the chemical oxidation of the sample (COD) according to the standard procedure accepted in ecology PNDF 14.1:2.19-95.
The principle of the method of the COD measurement is the bichromate oxidation with the direct potentiometry.
- drinking, natural, sea and waste water
- the extracts of soils and bottom sediments
- the extracts of microbiological, physiological and other media
