The technical field of on-line mass spectrometry detection, which is used for mass spectrometry to collect the gas phase components in the exhaust gas online.
With the development of the times, fully automated production lines, unmanned workshops and other production processes, such as steel smelting, cigarettes, food production, and garbage disposal will emit a large amount of exhaust gas into the atmosphere during the production process. On-line, real-time inspections are required at critical production stages. Control the quality and content of exhaust gas, the gas phase composition of exhaust gas in various industries, and carry out quantitative data collection at the same time to better improve the process upgrading of the production process.
The online time-of-flight mass spectrometer can collect exhaust gas online, which can be used for online detection and quantitative analysis. Due to the diverse environment of the production line, complex environmental factors such as high temperature, large particle dust pollution, and narrow space, the mass spectrometer cannot be placed on the production line in close proximity for high-precision detection. If the sampling pipeline is extended and the distance between the production line and the mass spectrometer is widened, it can avoid the mass spectrometry instrument being affected by the environment of the production line during online detection. However, extending the sampling pipeline will reduce the weakening of the solid particle exhaust gas acquisition signal.
In the case of high temperature, heating, baking production line mass spectrometer injection pipe should also be accompanied by the same temperature on the production line, quartz capillary is widely used in mass spectrometry injection, its advantage is high temperature resistance, with the pipe can be placed at any angle. Due to the large amount of particulate matter in the exhaust gas, the mass spectrometry capillary sampling is easy to clog and the effective injection volume is small, which makes it impossible to detect the trace amount of the species of interest in the process of collecting the gas phase composition in the exhaust gas through capillary injection.
According to the questions raised, the pipeline device for mass spectrometry online collection of gas phase components in tail gas is equipped with a bypass diaphragm pump to assist in extending the gas flow rate of the pipeline and enhance the injection volume of gas phase components in the tail gas collected by mass spectrometry online.
