Abstract: front page image
(EN)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.
(FR)Spectromètre de masse comprenant un piège à ions 2D ou 3D. Le piège à ions 2D comprend un piège à ions à ensemble de quadruple tige, chacune des tiges 1 comportant une fente qui permet aux ions de s'échapper du piège à ions. Le piège à ions 3D comprend une électrode annulaire centrale segmentée radialement, chaque segment radial présentant une fente qui permet aux ions de s'échapper du piège à ions. Les ions dotés de rapports masse-charge différents et/ou des polarités opposées peuvent être éjectés simultanément du piège à ions par des trajets de sortie différents.
