Interpretation Introduction
Interpretation:
The difference between the spectra of EI, field ionization and the CI sources is to be stated.
Concept introduction:
Ionization refers to the process in which an atom or a molecule obtains a positive or a negative charge by losing or gaining an electron. This results in the synthesis of an ion. There are a variety of ionization methods. These include chemical ionization, electron impact, electrospray ionization, field ionization etc.
