A quantity of electrons that will be used in the ionization event in an FTICR MS is preprogrammed. When the number of electrons produced reaches that number, the electron beam is turned off. This approach assures that the same number of electrons are used for every measurement and eliminates the variations due to fundamental characteristics of the electron sourcere and the variations in temperature due to changing ambient conditions.

Microfabricated cylindrical ion trap
InactiveUS6870158B1Stability-of-path spectrometersIsotope separationManufacturing cost reductionHigh pressure
A microscale cylindrical ion trap, having an inner radius of order one micron, can be fabricated using surface micromachining techniques and materials known to the integrated circuits manufacturing and microelectromechanical systems industries. Micromachining methods enable batch fabrication, reduced manufacturing costs, dimensional and positional precision, and monolithic integration of massive arrays of ion traps with microscale ion generation and detection devices. Massive arraying enables the microscale cylindrical ion trap to retain the resolution, sensitivity, and mass range advantages necessary for high chemical selectivity. The microscale CIT has a reduced ion mean free path, allowing operation at higher pressures with less expensive and less bulky vacuum pumping system, and with lower battery power than conventional- and miniature-sized ion traps. The reduced electrode voltage enables integration of the microscale cylindrical ion trap with on-chip integrated circuit-based rf operation and detection electronics (i.e., cell phone electronics). Therefore, the full performance advantages of microscale cylindrical ion traps can be realized in truly field portable, handheld microanalysis systems.

Multiply charged ions are trapped and accumulated in a spatially limited region before being injected into an ion trap mass spectrometer such as a Fourier transform ion cyclotron resonance mass spectrometer (FTICR MS). In the ion trap electron capture dissociation (ECD) and vibrational excitation dissociation are sequentially applied on ions of the same ion ensemble. The first dissociation process does not fragment all primary ions. Following the detection of the dissociation products, the primary ions that remain undissociated undergo the vibrational excitation and again, a part of them dissociate, and the fragments are detected. Thus, the same ion ensemble is used for two fragmentation processes. During these processes, further ions generated in the external ion source are accumulated in the spatially limited region for subsequent analyses.

The present invention comprises a method and system for accurate estimation of the ion cyclotron resonance (ICR) parameters in Fourier-transform mass spectrometry (FTMS / FT-ICR MS). The parameters are essential to estimating the mass to charge ratio of an ion from FT-ICR MS data, the intended purpose of the instrument. Achieving greater accuracy in the parameters assists in greater accuracy of the mass to charge ratio of an ion, and obtaining an accurate estimation of the mass to charge ratio of an ion further aides in detecting mass with sub-ppm accuracy. Estimating mass in this manner enhances identification and characterization of large molecules. The inventive method and system thereby enhances the data obtained by conventional FTMS by accurately estimating ICR parameters. Ultimately, accurate estimates of the masses of molecules and detection and characterization of molecules from FT-ICR MS data are obtained.

Method of Processing Mass Spectrometry Data

A method of processing Fourier Transform Mass Spectrometry (FTMS) data comprises carrying out a Fourier Trans-form of a part of a time domain transient and identifying from that transformed data signal peaks representative of the presence of ions. Once the peaks have been identified, the full transient is then transformed, and the peaks identified in the partial transient transform are used to locate true peaks in the transformed full transient. The number of ‘false’ peaks resulting from random noise has been found to correlate to the resolution, so that using a partial transient to identify true peaks reduces the risk of false peaks being included; nevertheless this information can then be applied to the full data set when transformed. As an alternative, different parts of the full data set can be transformed and then correlated; because any noise will be random, false peaks should occur at different places in the two partial transforms.

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 invention relates to measuring devices of an electrostatic Fourier transform mass spectrometer and measurement methods for the acquisition of mass spectra with high mass resolution. The measuring device includes electrostatic measuring cells according to the Kingdon principle, in which ions can, when appropriate voltages are applied, orbit on circular trajectories around the cylinder axis between two concentric cylindrical surfaces, which are composed of specially shaped sheath electrodes, insulated from each other by parabolic gaps, and can harmonically oscillate in the axial direction, independently of their orbiting motion. In the longitudinal direction, the two cylindrical surfaces of the measuring cell are divided by the parabolic separating gaps into different types of double-angled and tetragonal sheath electrode segments. Appropriate voltages at the sheath electrode segments generate a potential distribution between the two concentric cylindrical surfaces which forms a parabolic potential well in the axial direction for orbiting ions. The ion clouds oscillating harmonically in the axial direction in this potential well induce image currents in suitable electrodes, from which the oscillation frequencies can be determined by Fourier analyses.

An improved FT-ICR Mass Spectrometer has an ion source 10 which generates ions that are transmitted through a series of multipoles 20 to an ion trap 30. Ions are ejected from the trap 30, through a series of lens and multipolar ion guide stages 40–90, and into a measurement cell 100 via an exit / gate lens 110. The measurement cell is mounted in a vacuum chamber 240 and this assembly is slideably moveable into a bore of a superconducting magnet 400 which provides the magnetic filed to cause cyclotron motion of the generated ions in the cell 100. By minimising the distance between the source 10 and cell 100, and by careful alignment of the ion optics, the ions can travel at high energies right up to the front of the measurement cell 100. The cell 100 extends in the longitudinal direction of the magnet bore and is coaxial with that. The ratio of the sectional area of the magnet bore to the sectional area of the cell volume is small (less than 3). The magnet is asymmetric and is relatively short on the ion injection side. The cell 100 is supported from in front of the cell and electrical contact is from the rear thereof.
