A valuable tool for industries that require real-time monitoring of water quality

The BioMonitor measures total BOD (Biochemical Oxygen Demand) using a UV-VIS spectrophotometer. BOD is a measure of the amount of oxygen consumed by microorganisms as they decompose organic matter in water. The higher the BOD, the greater the amount of organic matter present in the water.

To measure BOD using the BioMonitor, water samples are collected and mixed with a nutrient solution that provides the microorganisms with the necessary nutrients for growth. The samples are then incubated for a specific amount of time, typically five days, during which the microorganisms consume the organic matter and release carbon dioxide.

After the incubation period, the carbon dioxide produced by the microorganisms is measured using the UV-VIS spectrophotometer. The spectrophotometer uses light to measure the absorbance of the carbon dioxide, which is directly proportional to the amount of BOD in the water sample.

The BioMonitor can perform this process automatically, using an integrated auto-sampler to collect and mix the water samples, and an incubator to maintain the samples at the appropriate temperature during the incubation period. The analyzer can then measure the BOD in real-time, providing continuous monitoring of water quality.
