质谱做的就是把东西拿出来再看看它是什么。
拿出来就是离子化
看看它就是质量分析
离子化在维基上就有6大类
# 1 Electron and chemical ionization
* 1.1 Electron ionization
* 1.2 Chemical ionization
* 1.3 Radioactive ion sources
* 1.4 Ion-attachment ionization
# 2 Gas discharge ion sources
* 2.1 Inductively coupled plasma
* 2.2 Microwave induced plasma
* 2.3 Glow discharge
* 2.4 Spark ionization
* 2.5 Closed drift ion sources
# 3 Desorption ionization
* 3.1 Aerosol laser desorption and ionization
* 3.2 Fast atom bombardment
* 3.3 Field desorption
* 3.4 Liquid metal ion sources
* 3.5 Surface-enhanced laser desorption/ionization
# 4 Spray ionization
* 4.1 Atmospheric pressure chemical ionization
* 4.2 Atmospheric pressure photoionization
* 4.3 Electrospray ionization
* 4.4 Probe electrospray ionization
* 4.5 Sonic spray ionization
* 4.6 Thermospray ionization
# 5 Ambient ionization
* 5.1 Desorption electrospray ionization
* 5.2 Direct analysis in real time
* 5.3 Matrix-assisted laser desorption electrospray ionization
# 6 Particle accelerators
* 6.1 Theory of Operation
质量分析主要通过磁场或电场分离不同质量的离子,大概有4种。
