1.Atmospheric pressure ionization(API), including atmospheric pressure chemical ionization(APCI) and electrospray ionization(ESI), is a new ionization mode and ion source. It has been gradually developed since 1980. As the most soft ionizaion technology, its ionization process generates at atmospheric pressure and its ionization efficiency is very high. Atmospheric pressure ionization technology is now routinely applied as liquid chromatography-mass spectrometry interface .
