[0002] Standard gas is a term used in the gas industry. Standard substances are measurement standards with uniform concentration, good stability, and accurate values. They have the basic functions of reproducing, preserving, and transmitting measurement values. In the fields of physical, chemical, biological, and engineering measurement, they are used to calibrate measuring instruments and measurement processes, evaluate the accuracy of measurement methods and the testing capabilities of testing laboratories, determine the characteristic values ​​of materials or products, and conduct measurement arbitration, etc. Standard gases are classified into binary, ternary, and multi-component standard gases.

[0003] Standard gases serve as the "metric benchmark" for gas analysis and detection. The consistency and stability of their component concentrations directly affect the accuracy of measurement results. In the preparation of multi-component standard gases, different component gases have large differences in molecular diffusion coefficients and different physicochemical properties. Current standard gas premixing devices have a single gas inlet method, which makes it inconvenient to control the sequence and speed of gas inlet, and is prone to problems such as uneven mixing, stratification, or local concentration deviation. Therefore, those skilled in the art have provided a multi-component premixing homogenization device for standard gases to solve the problems mentioned in the background art. Utility Model Content
