Nanocolor Biochemical Oxygen Demand test kits
985 822: Photometric determination of BOD5
Simple determination of the biochemical oxygen demand after 5 days (BOD5) of undiluted samples without using a control in accordance with DIN EN 1899-2-H52!
The oxygen enriched, undiluted sample is incubated in test tubes for 5 days at 20 ± 1°C in the dark. Determination of the dissolved oxygen after 5 days is based on the Winkler procedure, DIN EN 25813-G21
Reaction basis:
DIN method: the determination of the BOD5 is carried out with the so-called dilution principle. The oxygen concentration is determined immediately after preparation of the sample and again after a five-day incubation in Winkler-flasks.
Reaction basis analogous to DIN EN 1899-1-H51 and DIN EN 25813-G21.
