Zusammenfassung:Mass spectrometric system 501 with ion source, first RF funnel 7a, mass analyser (not shown) and ion mobility analyser 9c 9d. The first RF funnel 7a is non-collinear with the ion mobility analyser 9c 9d and they may be in separate vacuum chambers 1b 1c. A second RF funnel 7b may be arranged collinearly at the entrance of the ion mobility analyser. An RF multipole 11b may be arranged between the two RF funnels 7a 7b, which may operate as a filter or as a fragmentation cell receiving light from a light source 13. An additional ion mobility analyser 9a 9b may be between the first RF funnel 7a and RF multipole 11b, collinear with the first RF funnel 7a and located within its vacuum chamber 1b. Preferably the ion mobility analysers are TIMS analysers.
