摘要：
Owing to the rapid release of multi-component gas during the reaction process of energetic materials, the technical issues in sampling and transmission, spectral analysis, and quantitative analysis are elaborated by using the continuous real-time and full-component scanning detection method of mass spectrometry. The technical difficulties of the reliability and distortion mechanism of different mass spectrometry sampling interfaces, the overlap of spectra due to the synchronous coupling of reaction process and ionization, and quantitative analysis of multi-component gas are analyzed. Three representative reaction processes are selected to illustrate the secondary reaction of crystallization of the evolved gas from boiler slags, nonlinear analysis of the mass spectrum signal in CaS gasification, and quantitative analysis of the mass spectra of the evolved gas from the typical energetic material Fx. The results show that the quantitative mass spectrometry method, equivalent characteristic spectrum analysis(ECSA®), can be used to determine the sampling distortion and accurately analyze the mass change rate of multi-component gas. Based on the continuous dynamic information for the mass changes of the multi-component gas and the mass balance of materials, components, and elements, the ECSA® method enables accurate identification of multiple reaction processes. © 2023 China Ordnance Industry Corporation.
