Fourth, the product description
Standard gases are gaseous standard materials, also known as calibration gases, calibration gases, Standard Gases, Referance Gases, etc.
The standard gas is highly uniform, with good stability and accurate measurement standards, so the standard gas must have the basic function of recurring, preserving and transferring the value.
Used in the fields of physics, chemistry, biology and engineering measurement to calibrate measuring instruments and measuring processes, to evaluate the accuracy of measuring methods and the testing capabilities of testing laboratories, to determine the characteristic quantities of materials or products, and to perform quantitative arbitration.
Fifth, the main purpose
Mainly used for environmental monitoring, calibration standards, analytical instruments and so on.

Seven, product application
Large ethylene plants, ammonia plants and other petrochemical companies require dozens of pure gases and hundreds of multi-component standard mixtures during plant start-up, parking and normal production to calibrate and standardize the online use in the production process. Analytical instruments and instruments for analyzing raw materials and product quality. Standard gases can also be used for environmental monitoring, toxic organic matter measurement, automotive exhaust gas testing, natural gas BTU measurement, liquefied petroleum gas calibration standards, and supercritical fluid processes.
The standard gas is divided into binary, ternary and multi-standard gas according to the number of gas components; the gas distribution accuracy is characterized by the gas distribution tolerance and the analytical tolerance; the more common ones have the SE2MI gas distribution tolerance standard, but each company has There are corporate standards. The lowest concentration of the components is 10-6, and the number of components can be as many as 20 kinds.
Standard gas preparation methods can be performed by gravimetric analysis followed by chromatographic analysis or by standard delivery procedures.
Eight, matters needing attention
The standard gas is a standard substance, please keep it uniform and strictly observe the storage temperature range. The bottled gas product is a high-pressure filling gas, which should be used after being decompressed and pressure-reduced. The used cylinders are used for a long period of time. All expired cylinders must be sent to a department for safety inspection before they can continue to be used. When using the exhaust gas in each bottle of gas, the residual pressure in the bottle should be kept at 0.5MPa, and the minimum pressure should not be lower than 0.25MPa. The valve should be closed to ensure the gas quality and safety. Bottled gas products should be stacked in storage, storage and use. It is strictly forbidden to stack flammable gas and combustion-supporting gas. It is not allowed to be close to open flames and heat sources. Do not near fire, do not touch oil, do not expose to the sun, do not throw Do not hit, do not conduct arcing or arcing on the cylinder, and prohibit rough handling.
