3.1 Ion creation
As a rule, primary ions are created by electron bombardment inside the experimental device. Any other method can be used: photoionization, photodissociation with pair formation, collision with Rydberg atoms to form negative ions, Penning-type collision, laser ionization, etc.
The three most widely used ion creation methods today are electrospray ionization (ESI), Atmospheric Pressure Interface-Electrospray Ionization (API) and Matrix Assisted Laser Desorption Ionization (MALDI)
Once created, the ions are subjected to collisions with the buffer gas, usually helium, allowing them to dissipate the kinetic energy acquired during fragmentation, or the...
