Patent ID: 8853623

Claim:
An electrostatic mass spectrometer comprising: i. a pulsed ion source for ion packet formation; ii. an ion detector; iii. a multi-pass electrostatic mass analyzer providing an ion packet passage though said analyzer in a Z-direction and isochronous ion oscillations in the locally orthogonal direction X; iv. a pulse string generator for triggering said pulsed ion source at time intervals between adjacent pulses being at or around ten (10) times shorter than a flight time of said ion packets in the analyzer, and wherein the time intervals between at least a portion of start pulses being unique within the peak time width ΔT on the detector thereby yielding at least partially overlapped spectral signals; v. a data acquisition system recording of detector signal at the duration of said pulse string; vi. a main pulse generator for triggering both-said data acquisition system and said pulse string generator; and vii. a spectral decoder for reconstructing the at least partially overlapped mass spectra based on the detector signal and on the information on the preset time intervals of said start pulses.
