MULTI-REFLECTING TIME-OF-FLIGHT MASS SPECTROMETER WITH ISOCHRONOUS CURVED ION INTERFACE |
摘要 |
The present invention relates generally to a multi-reflecting time-of-flight mass spectrometer (MR TOF MS). To improve mass resolving power of a planar MR TOF MS (11), a spatially isochronous and curved interface (21) may be used for ion transfer in and out of the MR TOF analyzer (11). One embodiment comprises a planar MR TOF MS (11) with periodic lenses (14) in the field-free space, a linear ion trap (17) for converting ion flow into pulses and a C-shaped isochronous interface made of electrostatic sectors. The interface (21) allows transferring ions around the edges and fringing fields (13) of the ion mirrors (12) without introducing significant time spread. The interface (21) may also provide energy filtering of ion packets. The non-correlated turn-around time of ion trap converter (17) may be reduced by using a delayed ion extraction from the ion trap and excessive ion energy is filtered in the curved interface (21). |
