Description
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.
