Fund Project: Supported by the National Natural Science Foundation of China (Nos. 22076190, 21876176) and the HFIPS Director′s Fund (Nos. BJPY2021B08, YZJJ2022QN45, YZJJZX202009).

Concentration calibration is the premise of accurate quantitative detection of gas analyzer, and concentration calibration cannot be separated from gas dilution system. In this work, a novel wet gas preparation method (proportion-integral (PI) two-flow method) was established, and that a simple yet accurate gas dilution system with humidity control function based on PI two-flow method was developed, which was not affected by intermediate variables. Firstly, the performance of the humidifier, an essential part of the system, was investigated. The results showed that there was a certain fluctuation (96%-103%) in the relative humidity (RH) at the outlet of the humidifier. Therefore, the PI two-flow method was developed to reduce the influence of the fluctuation on the humidity control accuracy of the whole system. A dew point transmitter was used to measure the RH at the system′s outlet as a feedback signal to automatically adjust the ratio of dry and wet gas, thereby realizing accurate control of humidity. The wet gas was prepared by the following method, the dry gas passing through a self-made bubbling humidifier. Subsequently, the system′s response characteristics were investigated by step input and sinusoidal input under different flow rates and temperature conditions. The results showed that the RH control range of the system was 5%-100%. The flow rate of the system could be up to 1000 mL/min. The RH control accuracy could realize 0.026%RH (25 °C, 100%RH) (without considering the measurement deviation of the dewpoint transmitter). The setting time reached 38 s (25 °C, 500 mL/min). The system could track the sinusoidal input when the period was more than 175 s in 1000 mL/min. Finally, the application research of the system was implemented by using proton transfer reaction mass spectrometry (PTR-MS). As the RH of sampling air of PTR-MS gradually increased, the relative ratio of H₃O⁺ decreased, and the relative proportion of H₃O⁺(H₂O) increased. The above application showed that the new system could meet the application requirements of gas analysis instruments with large and continuous sampling flow rate in a wide humidity range (10%-100%). The new system would be expected to calibrate gas measurements instruments sensitive to humidity.
