I-analyzer yenza ngokuzenzekelayo indlela eqhelekileyo ye-dichromate oxidation. Itsala isampuli yamanzi rhoqo, yongeza iivolumu ezichanekileyo ze-potassium dichromate (K₂Cr₂O₇) oxidant kunye ne-concentrated sulfuric acid (H₂SO₄) kunye ne-silver sulfate (Ag₂SO₄) njenge-catalyst, kwaye ifudumeza umxube ukuze kukhawuleziswe i-oxidation. Emva kokugaya, i-dichromate eseleyo ilinganiswa nge-colorimetry okanye i-potentiometric titration. Isixhobo sibala uxinaniso lwe-COD ngokusekelwe ekusetyenzisweni kwe-oxidant. Iimodeli eziphambili zidibanisa ii-reactors zokugaya, iinkqubo zokupholisa, kunye neemodyuli zokuphatha inkunkuma ukuze kukhuseleke kwaye kuchaneke.
