Abstract (en)

[origin: EP0290712A1] In the eight-pole arrangement (5) used for holding and guiding ions having a low kinetic energy, an E-field in the desired ion movement direction is superimposed on the radially acting RF field, as a result of which, despite the kinetic energy of the ions remaining low, safe, rapid deflection to the mass spectrometer quadrupole (3) takes place and the response time and overall sensitivity of the arrangement can be significantly increased. <IMAGE>
