| 摘要 |
A multi-turn Time of Flight mass analyser 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 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 the mass analyser 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 5,8 may be sub-divided into a plurality of electric sector segments. |
