质谱仪是将物质粒子转换成离子并通过适当的电场、磁场将它们按空间位置、时间先后、飞行轨道稳定与否实现荷质比分离,并检测强度后进行物质成分分析的仪器。质谱仪主要由进样系统、真空系统、电学系统、检测系统和数据处理分析系统组成。质谱方法最早于1913年由J.J.汤姆逊确定, Mass spectrometer is the material particles into ions and through the appropriate electric field, magnetic field according to their location in space, time, flight orbit stability or not to achieve the charge-mass ratio, and the detection of intensity after the instrument for the analysis of the composition of matter. Mass spectrometer mainly by the injection system, vacuum system, electrical system, detection system and data processing and analysis system. The mass spectrometry method was first identified by J.J. Thomson in 1913,
