 Universal Measurement System for Gas-Exchange Metabolism based on the manometric measurement of pressure changes (respirometer) in a closed system
Applications
aerobic
- determination of soil respiration (DIN 19 737)
- AT4-determination oxygen consumption (cell respiration; composting, BOD-determination)
- determination of biodegradability OECD 301 F
- oxygen absorption by solid matter, etc.
anaerobic
- biogas build-up (fermentation)
- gas discharge (waste dumps, sewage sludge, etc.)
aerobic and anaerobic
- quantifying the CO2 content of accumulated biogas
- pressure differences, changes in pressure patterns, etc.
