What are the industrial gas standard gases?
Author：
Standard gas refers to gas industry. Reference materials are measurement standards with uniform concentration, good stability and accurate quantity value. They have the basic function of reproducing, saving and transferring quantity values. They are used in the fields of physics, chemistry, biology and engineering measurement to calibrate measuring instruments and measurement processes, evaluate the accuracy of measurement methods and the detection capability of testing laboratories, determine the characteristic quantity values of materials or products, and arbitrate quantity values.
1. Common standard gases include: gas alarm standard gases, power and energy standard gases, petrochemical standard gases, environmental protection monitoring standard gases, medical and health standard gases, instrument standard gases, etc.
2. The standard gas can also be used for environmental monitoring, toxic organic matter measurement, automobile exhaust gas test, natural gas BTU measurement, liquefied petroleum gas calibration standard, supercritical fluid process, etc.
3. Large ethylene plants, ammonia plants and other petrochemical enterprises need dozens of pure gas and hundreds of multi-component standard gas mixtures in the process of unit startup, shutdown and normal production to calibrate and calibrate online analytical instruments and instruments used in the production process to analyze the quality of raw materials and products.
