Abstract:
A mass analyzing apparatus and system are disclosed for time-of-flight (“TOF”) mass spectrometry analysis. A representative system includes a first electrostatic mirror prism to reflect a first ion beam and provide an intermediate ion beam having an intermediate TOF focus and having a spatial dispersion of ions proportional to ion kinetic energies; and a second electrostatic mirror prism to reflect the second ion beam and converge the spatial dispersion of ions to provide a third, recombined ion beam having an output TOF focus; and an ion detector arranged at the output TOF focus to receive and detect the ions of the third ion beam. A bandpass filter may be arranged at the intermediate TOF focus to selectively allow propagation of ions of the second ion beam having a selected range of ion kinetic energies. Configurations having additional electrostatic mirror prisms are disclosed, including for tandem MS-MS and selectable time-of-flight.

Claim (Index 27):
