A mass spectrometer is disclosed comprising a 2D or 3D ion trap. The 2D ion trap comprises a quadrupole rod set ion trap wherein a slot is provided in each of the rods 1 to allow ions to be ejected radially from the ion trap. The 3D ion trap comprises a central ring electrode which is radially segmented and wherein a slot is provided in each radial segment to allow ions to be ejected radially from the ion trap. Ions having different mass to charge ratios and/or opposite polarities may be simultaneously ejected from the ion trap via different exit pathways.
