摘要
针对含能材料反应过程多组分气体的同时快速释放特点,利用质谱的连续实时、全组分扫描的检测方式,详细阐述了其采样传输、图谱解析、定量分析等方面存在的技术难题,分析不同质谱采样接口的可靠性与失真机理、反应过程与质谱电离同步耦合作用下的图谱重叠、多组分气体质谱定量等难点。选取3类代表性反应过程具体阐述了锅炉结渣物的逸出气体冷凝结晶二次反应、CaS气化反应过程质谱信号非线性解析及典型含能材料Fx逸出气体质谱定量解析。结果表明,利用质谱定量分析方法———等效特征图谱法(Equivalent characteristic spectrum analysis)ECSA?,实现了对采样失真的判断与多组分气体质量变化率的精准解析,通过解析后的多组分质量变化连续动态信息,基于物料、组分、元素质量平衡,实现对多重反应过程的精准辨识。
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.
