基于傅里叶变换红外气体分析仪的零气发生器检测方法研究OA

The performance of a zero-gas generator directly affects the accuracy of the subsequent analysis results.To determine whether the performance meets the requirements of the national standard GB 18285-2018,a detection method incorporating a Fourier-transform infrared(FT-IR)gas analyzer was designed.Various nationally certified standard gases were dynamically diluted to the specific concentrations required by the national standard for detection,which are referred to as"reference standard gases"in the text.The FT-IR gas analyzer measured the responses of the reference standard gases,and the detection limits of the analyzer were determined for various reference standard gases.National certified standard gases were successively input into zero-gas generators from three different manufacturers:A,B,and C.The responses of the output gases were measured using the FT-IR gas analyzer and then divided by the responses of the reference standard gases.The results showed that the zero-gas generators from all three manufacturers met the requirements of the national standard.The robust performance of this method for the calibration and assessment of detection capability of zero-gas generators improves their detection efficiency and reliability,providing an important reference for the quality detection of zero gas.
