质谱 (massspectrometer,MS)分析是分析化学中进行物质成分和结构分析的主要技术之一 ,其基本原理是将分析样品在特定的条件下转变为高速运动的离子 ,这些离子根据质量、电荷比的不同在静电场和磁场的作用下得到分离 ,然后用特定的检测器记录各种离子的相对强度并形成质谱图。
Mass spectrometry (MS) analysis is one of the main techniques for the analysis of the chemical composition and structure in analytical chemistry. The basic principle is to change the analytical sample into high-speed moving ions under certain conditions. These ions are classified according to mass, charge ratio Different in the electrostatic field and the role of the magnetic field was separated, and then use a specific detector to record the relative intensity of various ions and the formation of the mass spectrum.
