The analyzer cell works on the principle of mass spectrometry and is
set to the mass of helium (m/e = 4).
m/e = atomic mass of the particle/number of electrons lost on
ionization
The principle of magnetic deflexion spectrometry is as follows.
The neutral molecules of the gas being analyzed pass into an
ionization chamber (or source of ions) where they are bombarded by
an electron beam generated by a heated tungsten filament. A large
number of the molecules are transformed into ions.
