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: An ion guide is disclosed comprising one or more layers of intermediate planar, plate or mesh electrodes. A first array of first electrodes is provided on a upper surface and a second array of second electrodes is arranged on a lower surface. An ion guiding region is formed within the ion guide. One or more transient DC voltages or potentials are preferably applied to the first and second array of second electrodes in order to urge, propel, force or accelerate ions through or along the ion guide.

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.
