Description of standard gas:
Standard gas is a gas standard material. Standard gases are highly uniform, repeatable and accurate measurement standards. They have the basic function of reproducing, preserving and transmitting values. They are used to calibrate measuring instruments and measurements in the fields of physics, chemistry, biology and engineering measurements. process, evaluate the accuracy of measurement methods and the testing capabilities of testing laboratories, determine the characteristic values of materials or products, conduct value arbitration, etc. The standard gas is divided into binary, ternary and multi-element standard gas according to the gas component fraction. The gas distribution accuracy requirements are characterized by gas distribution tolerance and analysis tolerance. The preparation method can be gravimetric, and then checked by chromatographic analysis, or it can be based on Standard delivery procedures are used for delivery.

Application of standard gas:
Standard gas is used in gas product quality control, instrument calibration and Calibration, atmospheric environmental pollution monitoring, medical health and clinical testing, building and home environment monitoring, etc. In large-scale ethylene plants, synthetic ammonia plants and other chemical plant equipment, dozens of pure gases and hundreds of multi-component standard gases are required during startup, shutdown and normal production processes to calibrate and calibrate the online analytical instruments used in the production process. Instruments for analyzing raw material and product quality. Standard gases are also widely used in environmental monitoring, toxic organic matter measurement, automobile exhaust gas testing, natural gas B measurement, liquefied petroleum gas calibration standards, supercritical fluid processes, etc.

Common uses of standard gas
1. Used for quality control of gas products, In order to ensure that the quality of the gas products produced meets national standards or industry standards, daily supervision and calibration of the products must be carried out regularly. Most gas analysis instruments are relative measuring instruments and must use standard gas as the quantitative standard to ensure the accuracy of the measurement results. 2. Used for the verification and calibration of instruments and meters. The modern production process, from the verification of raw materials, the control of the production process, to the verification and evaluation of the final product quality, is inseparable from various types of Instrumentation. In order to ensure efficient and high-quality production, various standard gases need to be used regularly to verify or calibrate the instruments. Especially after online instruments have been used or repaired for a long time, standard gases are needed to calibrate the scales.
3. Used for monitoring atmospheric environmental pollution. As environmental pollution becomes increasingly serious, the problem of environmental pollution control is urgent. Various countries have formulated environmental protection laws, environmental standards and maximum levels of harmful substances in the atmosphere of residential areas ( Allowed) concentration, etc. Therefore, environmental monitoring and management and air pollution rating are more important. In order to ensure the accuracy of monitoring and the effectiveness of governance, various instruments and instruments for monitoring need to be regularly calibrated with accurate and reliable standard gases.
4. Used in medical, health and clinical testing. In recent years, my country's standard gases have begun to be used in medical, health and clinical testing, such as blood gas analysis, lung function measurement, bacterial culture, respiratory metabolism measurement, radioactive tracer 5. Used for environmental monitoring of buildings and homes. With the improvement of people's living standards, people have higher and higher requirements for the decoration of buildings and homes. Hazardous substances in indoor building decoration materials must be strictly controlled. Control and accurately detect, such as benzaldehyde, ammonia, etc. To accurately measure the content of harmful gases in the home environment, corresponding standard gases are needed to calibrate the instrument.
