ABSTRACT:
The molecules of a sample are ionized and the produced ions are subjected to a dispersion according to their kinetic energies in an electrostatic field and then to a dispersion according to their mass numbers in a magnetic field. Of the mass-dispersed ions, some having a specific mass number are focussed by means of a lens system disposed between the electrostatic and magnetic fields and the focussed ions are detected by an ion detector.
