摘要： A mass spectrometer is disclosed comprising a mass filter for separating ions according to their mass to charge ratio. The mass filter comprises a plurality of electrodes wherein ions are radially confined within the mass filter by the application of AC or RF voltages to the electrodes. One or more transient DC voltages or one or more transient DC voltage waveforms are progressively applied to the electrodes so that ions having a certain mass to charge ratio are separated from other ions having different mass to charge ratios which remain radially confined within the mass filter.

摘要： A mass spectrometer is disclosed comprising a collision cell wherein ions having substantially different mass to charge ratios are arranged to be transmitted through at least a portion of the collision cell at substantially the same time and with substantially the same velocity preferably by means of one or more transient DC voltages or one or more transient DC voltage waveforms which are applied to the electrodes forming the collision cell so that ions are urged through the collision cell at a constant controlled velocity. By appropriate setting of the velocity of the DC voltage or DC voltage waveform passing along the length of the collision cell an efficient collision cell is provided which is able to fragment ions having considerably different mass to charge ratio at substantially the same time in an optimal manner.

摘要： A mass spectrometer is disclosed comprising an ion trap wherein ions which have been temporally separated according to their mass to charge ratio or ion mobility enter the ion trap. Once at least some of the ions have entered the ion trap, a plurality of ion trapping regions are created along the length of the ion trap in order to fractionate the ions. Alternatively, the ions may be received within one or more axial trapping regions which are translated along the ion trap with a velocity which is progressively reduced to zero.

摘要： A mass spectrometer is disclosed comprising an ion mobility spectrometer and an ion gate. A collision cell is arranged downstream of the ion gate. The operation of the ion mobility spectrometer and the ion gate are synchronised so that only ions having a particular mass to charge ratio and a desired charge state are onwardly transmitted to the collision cell.

摘要： A mass spectrometer includes an ion mobility spectrometer or separator arranged upstream of a collision or fragmentation cell. Ions are separated according to their ion mobility within the ion mobility spectrometer or separator. The kinetic energy of the ions exiting the ion mobility spectrometer or separator is increased substantially linearly with time in order to optimize the fragmentation energy of ions as they enter the collision or fragmentation cell. During the time that the potential of the ion mobility spectrometer or separator is being varied, the potential of ion-optical components upstream of the ion mobility spectrometer or separator such as an ion source, ion guide, quadrupole mass filter, optional second collision or fragmentation cell and an ion trapping device are kept constant.

摘要： A mass or mass to charge ratio selective ion trap is disclosed which directs ions into a small ejection region. A RF voltage acts to confine ions in a first (y) direction within the ion trap. A DC or RF voltage acts to confine ions in a second (x) direction. A quadratic DC potential well acts to confine ions in a third (z) direction within the ion trap. The profile of the quadratic DC potential well progressively varies along the second (x) direction.

摘要： A mass spectrometer is disclosed comprising a mass selective ion trap or mass analyzer arranged upstream of an ion guide. Ions are scanned out of the mass selective ion trap or mass analyzer and are received in one or more axial potential wells created or formed within the ion guide. One or more transient DC voltages or potentials are preferably applied to the ion guide in order to create a plurality of axial potential wells which are translated along the length of the ion guide. Ions are released in packets from the exit of the ion guide and are orthogonally acceleration into a drift or flight region of an orthogonal acceleration Time of Flight mass analyzer with a relatively high duty cycle.
