IMPROVED SPACE FOCUS TIME OF FLIGHT MASS SPECTROMETER |
摘要 |
A Time of Flight mass spectrometer is disclosed wherein a fifth order spatial focusing device is provided. The device which may comprise an additional stage in the source region of the Time of Flight mass analyser is arranged to introduce a non-zero fifth order spatial focusing term so that the combined effect of first, third and fifth order spatial focusing terms results in a reduction in the spread of ion arrival times AT of ions arriving at the ion detector. |
