Ion’s separation in the static fields: quadrupole electric and homogeneous magnetic

The behaviour of ion packet in the crossing static electromagnetic fields is investigated in the article. Homogenous transverse magnetic field is applied to quadrupole analyser which works in the static mode. A number of finite trajectories and the conditions for keeping ions in the canal of the device are determined by analytical methods. The initial conditions and parameters of the fields are formulated when the system works as an ion’s trap or farvitron.
