四种新型火药的场解吸和解吸电子轰击质谱研究

Study on Field Desorption Mass Spectra and Desorption Electron Impact Mass Spectra of Four New-type Gunpowders

本文采用FDMS和DElMS对4种新型火药进行了质谱分析,均得到了很强的分子离子峰和特征碎片峰,并对样品A进行了DEIMS的亚稳分析,得出了该类化合物的裂解规律为:M-n(NO),M-n(O),M-n(NO_2),M-n(HNO_2),M-n(OH)等。

The paper reported field desorption and desorption electron impact mass spectra of four new-type gunpowders. The two methods gave very intense molecular ion peaks and characteristic fragment ion peaks. The general features of mass spectra of the compounds are (M - nO) . (M- nNO) . (M-nNO2) , (M-nHNO2) , (M-nOH). The sample A was studied by using DEIMS metastable ion technique.
