Abstract (en)

[origin: US4694168A] The spectrometer includes an ion source, an ion mirror receiving the ions issued from the source, a first detector placed so as to receive the ions reflected by the mirror and a second detector disposed behind the mirror, all these components forming an assembly of axial symmetry. A reflex spectrum of the ions reflected by the mirror and received by the first detector can be obtained in parallel with a spectrum of the neutral species which may have appeared as a result of in flight decompositions of metastable ions and which are received by the second detector. This arrangement is particularly adapted to the study of metastable ions, processing means being provided for producing correlated reflex spectra where the contributions of ion fragments corresponding to received neutral fragments is enhanced.
