摘要: An open electrostatic trap mass spectrometer is disclosed for operation with wide and diverging ion packets. Signal on detector composed of signals corresponding to multiplicity cycles, called multiplets. Using reproducible distribution relative intensity within multiplets, the signal can be unscrambled relatively sparse spectra, such as spectra past fragmentation cell tandem spectrometer, mobility differential separators. Various embodiments are provided particular pulsed sources converters orthogonal accelerators, guides, traps. The method apparatus enhance duty cycle converters, improve space charge tolerance analyzer extends dynamic range time-of-flight detectors.
