Quantitative measurement of isotope ratios by time-of-flight mass spectrometry |
摘要 |
A mass spectrometer includes a pulsed ion source that generates an ion beam comprising a plurality of ions. A first timed ion selector passes a first group of ions. A first ion mirror generates a reflected ion beam comprising the first group of ions that at least partially compensates for an initial kinetic energy distribution of the first group of ions. A second timed ion selector passes a second group of ions. A second ion mirror generates a reflected ion beam comprising the second group of ions that at least partially compensates for an initial kinetic energy distribution of the second group of ions. A timed ion deflector deflects the second group of ions to a detector assembly comprising at least two ion detectors which detects the deflected ion beam.
