Conclusion
Organic Mass Spectrometry: Principle, introduction and ionization methods

Organic mass spectrometry should be considered as an analytical technique involving chemical reactivity in addition to physical measurements, because it involves a stage in which ions are produced prior to separation, and their intensity is measured as a function of the m/z ratio. This characteristic has led to the development of a large number of ionization sources, the use of which must be adapted to the physico-chemical properties of the compounds to be analyzed [P 2 646] .
