摘要: An ion guide is disclosed comprising a plurality of electrodes. A first device is arranged and adapted to apply a RF voltage to at least some of the electrodes in order to form, in use, a pseudo-potential well which acts to confine ions in a first direction within the ion guide. A second device is arranged and adapted to apply a DC voltage to at least some of the electrodes in order to form, in use, a DC potential well which acts to confine ions in a second direction within the ion guide. A third device is arranged and adapted to cause ions having desired or undesired mass to charge ratios to be mass to charge ratio selectively ejected from the ion guide in the second direction.

摘要: A non-linear ion guide is disclosed comprising a plurality of electrodes. An ion guiding region is arranged between the electrodes, and the ion guiding region curves at least in a first direction. A DC voltage is applied to at least some of the electrodes in order to form a DC potential well which acts to confine ions within the ion guiding region in the first direction.

摘要: A mass spectrometer is disclosed comprising a Time of Flight mass analyzer comprising an ion detector comprising an Analog to Digital Converter. Signals from the Analog to Digital Converter are digitized and the arrival time and intensity of ions are determined. The arrival time T0 and intensity S0 of each ion arrival event is converted into two separate intensities S(n),S(n+i) which are stored in neighboring time bins T(n), T(n+1).

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 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.
