Climate, respiration gases

COj/Oj in the Off-Gas CO2 evolution from a bioreactor is closely related to the physiological state and the activity of microorganisms in a bioreactor because CO, evolves as a result of catabolism and respiration by microorganisms or cells. Therefore, it is helpful to measure the content of CO2/O2 in the exhaust gas in order to understand the physiological climate of a bioreactor. The CO2 and O2 content in the exhaust gas are taken from the streamline and analyzed by infrared spectrophotometer (CO2) and galvanic cell probe (O,). The wet off-gas must be desiccated before being introduced into the gas analyzer.
