PQ-2 Gas Reference Material Preparation Device
Introduction
 PQ-2 gas reference material preparation device has important application value and wide application potential. Not only can standard gases of various inorganic substances and organic substances be prepared, but also standard gases that cannot be purchased, standard gases that are difficult to store and standard gases that are not easy to prepare can be solved by PQ-1 gas standard substance preparation device. For example, standard gases such as methyl mercaptan, ethyl mercaptan, methyl sulfide, dimethyl disulfide, methylamine, ethylamine, trimethylamine, methanol, ethanol, formaldehyde, acetaldehyde, SO2, NO2, SO2F2, S2OF10, etc. have been prepared by using the device. In addition, users can carry out on-line, off-line or on-site standard gas generation source use of the device according to needs, and complete various scientific research, instrument calibration, sensor calibration, on-site qualitative and quantitative determination, etc.
The device can be used to prepare binary or multi-component standard mixed gas with required concentration for various inorganic substances and organic substances in gas state or liquid state at normal temperature and pressure. The device can be used as a standard gas generating source in the processes of quantitative determination, instrument calibration, on-site monitoring and leak detection, new product development, reaction process control, etc. in production departments such as environmental protection, industrial hygiene, scientific research, teaching, chemical industry, petrochemical industry, civil air defense, electric power, transportation, military industry, industrial and mining, etc. The device is a new type static gas distribution device (patented product) with dynamic gas distribution characteristics. It has the characteristics of fast gas distribution speed, on-demand distribution, strong applicability; simple operation, standardization *, easy to master; small size, light weight, easy to carry, etc. The accuracy, repeatability and stability of the device are better than those of the general gas distribution device (performance-price ratio).
