Determination of anaerobic degradation processes: biogas determination
Anaerobic degradation processes take place in the absence of oxygen. In order to be able to fill the gas space above the sample with inert gas the measuring bottle has a septum sealed nozzle. When anaerobic degradation has taken place the dissolved CO 2 can be driven off and then removed from the gas space by means of a CO 2 absorber.
The resulting pressure difference is proportional to the CO 2 concentration, the remaining overpressure is proportional to the methane concentration. The degradation process can be comfortably followed in the "pressure" operating mode.
