【摘要】 本文主要采用EI--MS技术,配以直接进样方式,控制源温和进样杯温等手段,使被分析的混合物样品分级地挥发。在测得大量样品碎片峰的基础上择出最典型的峰。讨论了碎裂机理,结合红外光谱和高效液相色谱分析的结果,确定了样品分子的基本结构式。更多还原

【Abstract】 A organic unknown sample was analysed with Electron Impact-Mass Spectrometry (EI-MS), , Infrared Spectrophotometry and High Performance Liquid Chromatography, and a temperature . programancc trchnique were used in MS analytical work. The fragmentation pathways of molecular were discussed in this paper. And data obtained by instruments as before were used for identification of molecular stracture. The structure of pesticide emulsifler was confirmed, and molecular weight is 758.更多还原
