WTW OxiTop® Control AN6 / AN12 - Determination of anaerobic degradation processes: biogas determination
Laboratory procedures for determination of biodegradability according to DIN EN 29 408 / ISO 9408 / OECD 301 F

Anaerobic degradation processes take place in the absence of oxygen. A septum sealed bottle nozzle fills the head space above the sample with inert gas. When anaerobic degradation has taken place, the dissolved CO2 can be driven off and then removed from the head space by means of a CO2 absorber. The resulting pressure difference is proportional to the CO2 concentration; the remaining overpressure is proportional to the methane concentration. The degradation process can be conveniently observed in the "pressure" operating mode.


Oxi Top® Control OC 110
With the global expansion of wastewater treatment, soil remediation, and waste treatment, the study and monitoring of biological cleaning treatments becomes increasingly important.
Biological tests are an important component, in addition to the usual physical-chemical measuring methods. In order to determine the microbial activity in and biodegradability of foodstuffs, pollutants, harmful substances or waste substances, respiration (depletion) measurements are often performed. In these measurements the respiration of the organisms is determined under defined conditions as the oxygen uptake or release of carbon dioxide.
Measurements are carried out via closed systems using the OxiTop®-C in combination with the OC 110 controller. Depending on the application, specially adapted measuring vessels are available, all of which are equipped with the necessary connection thread and some are autoclavable. Specialty packages are available with everything needed for a particular application.
