摘　　要：Explosive is very important for military affairs and civil affairs.So analysis of this kind of compounds is very important and useful,especially determining the relative molecular mass.It is very difficult to determine the molecular ions,because this kind of material is easy to decompose when heating in the ion source by gas chromatography-mass spectrometry.Meanwhile,the adducted ions are very serious when analyzing by liquid chromatography-mass spectrometry.The paper presents a new method to determine the molecular ions using ESI MS by computer.The method is satisfactorily used to determine the molecular ions of RDX.Explosive is very important for military affairs and civil affairs.So analysis of this kind of compounds is very important and useful,especially determining the relative molecular mass.It is very difficult to determine the molecular ions,because this kind of material is easy to decompose when heating in the ion source by gas chromatography-mass spectrometry.Meanwhile,the adducted ions are very serious when analyzing by liquid chromatography-mass spectrometry.The paper presents a new method to determine the molecular ions using ESI MS by computer.The method is satisfactorily used to determine the molecular ions of RDX.
