| 摘要 |
A multiturn time of flight mass (TOF) spectrometer is disclosed comprising a first electric sector 5 and a second electric sector 8. The second electric sector 8 is arranged orthogonal to the first electric sector 5. Ions may make multiple loops, orbits or circuits of the mass analyser before being detected and mass analysed, enabling a high resolution mass analyser to be provided. According to another embodiment (see Figure 3) the mass analyzer may have an open-loop geometry wherein the first electric sector is elongated and further electric sectors are arranged in a staggered manner along the length of the first electric sector. The first and second electric sectors 5 and 8 may be sub-divided into a plurality of electric sector segments. |
