| 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. |
