Exhaust Gas DetectorExhaust gas analyzer BLBIO-MS9000 Mass spectrometry gas analyzers 1) Import key components directly on an international scale. 2) Complete system design technology Specialized and targeted design of complete systems. 3) The complete set of system operation technology is completed by senior engineering and technical personnel who have received professional training from H&B's headquarters and independently completed the operation task. 4) Provide efficient whole-process technical services and include personnel training. 5) Biological fermentation tail gas CO2 and O2 analysis complete system configuration scheme System Description:1) In the process of biological fermentation, the respiratory quotient RQ value is very important. In order to obtain the RQ value in real time, it is necessary to detect the percentage of CO2/O2 in real time. This time, the oxygen analyzer and the carbon dioxide analysis system software and hardware integration of the biological fermentation tail gas analysis system are used to continuously detect the content of CO2 and O2 online, and it has high reliability and high stability. Provide real-time and reliable data for bioengineering research. It can detect the change of tail gas during the fermentation process of 12 fermenters at the same time, and can easily control the switch for the measurement of tail gas of each fermenter through the software. 2) Exhaust oxygen and carbon dioxide determination: detect the changes in the concentration ofCO2 andO2 in the exhaust gas, and combine the parameters of the fermentation liquid volume (weight), air flow, tank pressure and other parameters in the fermentation process to calculate the changes of OUR, CER, K La and μ, and then combine with other online and offline data to analyze the multi-scale problems in the fermentation process. Indirect parameter calculations must be performed with high-precision, low-drift gaseous oxygen and carbon dioxide determinations that meet the following requirements: l The sensitivity of the minimum content of gas components should be 0.01% (V/V), and the range and zero drift should be stable at ≤±1%FS/7d. l With different range switching, the oxygen analyzer should be based on air content, e.g. 18% to 21% for a span of 3%. l Standard gas and linearity correction function, to meet the slope and linearity requirements of the instrument, that is, linearity error ≤±1%FS. l Pretreatment of fermentation broth tail gas to overcome the influence of escaping liquid and saturated water vapor content at different temperatures on the actual measurement. |
