Product Description: Nitrification Inhibitor B 50mL
Nitrification Inhibitor B 50mL is a specialized BOD (Biochemical Oxygen Demand) testing reagent supplied by Tintometer GmbH / Lovibond, Germany. The product shown in the image is identified by Order Code 2418642 and is supplied in a 50 mL bottle. It is designed for use in water analysis and BOD measurement procedures where the oxygen consumption caused by nitrifying bacteria needs to be suppressed.
During BOD testing, nitrifying bacteria can consume dissolved oxygen in addition to the microorganisms responsible for degradation of organic matter. This additional oxygen consumption can affect the BOD result. Nitrification Inhibitor B is used to suppress the activity of nitrifying bacteria so that the measured BOD more specifically represents the oxygen requirement associated with the degradation of organic substances.

Applications of Nitrification Inhibitor B
BOD Testing
Nitrification Inhibitor B is primarily used during Biochemical Oxygen Demand (BOD) analysis. It helps suppress the oxygen consumption of nitrifying microorganisms so that the BOD measurement can focus on the oxygen demand associated with organic matter degradation.
Water Quality Analysis
The product is identified by the manufacturer as a reagent for water analysis. It can therefore be used in laboratory procedures related to wastewater, environmental water and other samples requiring BOD determination.
Nitrification Suppression
Nitrifying bacteria can contribute additional oxygen consumption during BOD measurement. The use of Nitrification Inhibitor B helps suppress this activity and can be particularly relevant when nitrification would otherwise influence the BOD result.
Lovibond BD 600 BOD System
Lovibond documentation lists Nitrification Inhibitor B 50 mL, Order Code 2418642 as an accessory/reagent for the BD 600 BOD Measurement System.
Recommended Use in BOD Measurement
According to the Lovibond BD 600 instructions, the recommended quantity of Nitrification Inhibitor B depends on the selected BOD measurement range. For example, for the 0–40 mg/L range, the manual recommends 10 drops for a 428 mL sample. Other measurement ranges use different sample volumes and inhibitor quantities. Therefore, the manufacturer’s instructions should be followed for the specific BOD range and instrument being used.
