| 摘要 |
The present invention relates to a method and to a mass spectrometer and uses thereof for detecting ions or subsequently-ionised neutral particles from samples. The method for operating a time-of-flight mass spectrometer for analysis of a first pulsed ion beam, the ions of which are disposed along the pulse direction, separated with respect to their ion masses, is characterised in that the ions of at least one individual predetermined ion mass or of at least one predetermined range of ion masses can be decoupled from the first pulsed ion beam as at least one decoupled ion beam and the first ion beam and the at least one decoupled ion beam are analysed. |
