摘要： A measuring cell of an ICR mass spectrometer and a method of operating a measuring cell of the ICR mass spectrometer. The method and system trap ions in a first compartment of the ICR measuring cell by generating an electric potential well in the direction of the magnetic field with a minimum of the electric potential well located inside the first compartment. The method and system excite cyclotron motion of the ions trapped in the first compartment. The method and system transfer at least a part of the excited ions from the first compartment to a second compartment of the ICR measuring cell by displacement of a position of the minimum of the electric potential well from the first compartment to the second compartment. The ions are transferred by displacing the position of the minimum of the electric potential well from the first compartment to the second compartment preferably over a period of time equal to or longer than a characteristic period of ion oscillations along the direction of the magnetic field in the electric potential well. The method and system detect ion cyclotron motion of at least a part of the ions in the second compartment.

摘要： A method and system for deconvolution of a frequency spectrum obtained in an ICR mass spectrometer based on a detection of ion oscillation overtones of the M-th order (where the integer M>1). A plurality of frequency peaks is collected within the frequency spectrum corresponding respectively to oscillations of different groups of ions, and associates at least one of the frequency peaks having a frequency f and a measured amplitude A with a particular group of the ions. The method and system identify whether the frequency peak is related to one of an overtone frequency, a subharmonic frequency, a higher harmonic frequency, or a side-shifted frequency of the oscillations of the different group of ions. The method and system derive calculated amplitudes of the overtone frequency peaks associated with the groups of ions by incorporating measured amplitudes of the frequency peaks related to the subharmonic frequency, the higher harmonic frequency, or the side-shifted frequency associated with the groups of ions into the calculated amplitudes of the overtone frequency peaks. The method and system generate a deconvoluted frequency spectrum including the overtone frequency peaks associated with the different groups of ions.
