This shows the mass to charge (m/z) ratio and abundance of each ion that reaches the detector. Given that all ions produced by electrospray ionisation and most of the ions by electron ionisation have a 1+ charge, the m/z is effectively the mass of each ion.
WebMay 1, 2024 · The spectrometers use electromagnetic fields to accelerate the ions, this effect only occurs if the species are charged as the field will not accelerate a neutral particle. For example, in the magnetic sector machine, the ions are formed in an ionization chamber, accelerated in a uniform electric field and shot into the magnetic sector where ...
