About this item
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 side-mounted connections, which are sealed with septa. When anaerobic degradation has taken place the dissolved CO₂ can be driven off and then removed from the gas space by means of a CO₂ absorber. The resulting pressure difference is proportional to the CO₂ concentration, the remaining over-pressure is proportional to the methane concentration. The degradation process can be comfortably followed in the “pressure” operating mode.
