A band gap mass filter for separating particles of mass (M1) from particles of mass (M2) in a multi-species plasma includes a chamber defining an axis. Coils around the chamber generate an axially aligned magnetic field defined (B=B0+B1 sin t), with an antenna generating the sinusoidal component (B1 sin t) to induce an azimuthal electric field (E) in the chamber. The resultant crossed electric and magnetic fields place particles M2 on unconfined orbits for collection inside the chamber, and pass the particles M1 through said chamber for separation from the particles M2. Unconfined orbits for particles M2 are determined according to an - plot ##EQU1##

where 0 is the cyclotron frequency for particles with mass/charge ratio M, and wherein 0=B0/M and 1=B1/M.
