摘要： A time-of-flight mass spectrometer capable of cutting out a major portion of carrier gas-derived ions ahead of the ion reservoir. The ion source is of the electron impact type and has source magnets for deflecting some of the produced ions away from the center axis of the ion reservoir. Electrostatic lenses for promoting the deflection of the ions caused by the source magnets and a differentially pumped slit for cutting off the deflected ions are mounted downstream of the ion source.

摘要： A novel instrument and method for TOF/TOF mass spectrometry is offered. A spiral trajectory time-of-flight mass spectrometer satisfies the spatial focusing conditions for the direction of flight and a direction orthogonal to the direction of flight whenever ions make a turn in the spiral trajectory. An ion gate for selecting precursor ions is placed in the spiral trajectory of the spiral trajectory time-of-flight mass spectrometer. Electric sectors are placed downstream of the ion gate.

摘要： A tandem mass spectrometry system has a first mass spectrometer for creating and extracting precursor ions. The ions are introduced into a decelerating electric field at a slight angle to the direction of the electric field which is formed by first through third electrodes. An accelerating electric field perpendicular to the decelerating electric field is applied at the instant when the ions arrive at the midpoint between the second and third electrodes at which the velocities of the ions in the direction of the decelerating field are zero.

摘要： Mass analysis method and mass spectrometer in which the S/N of mass spectra does not deteriorate due to accumulation if an ionization method, such as MALDI, producing spectral intensities that are not uniform in time is employed. Every given number of collected mass spectra are accumulated and stored to produce primary accumulation mass spectra. After the measurements, some of the stored primary accumulation spectra are selected according to a given rule based on a time trace of the intensities of the primary accumulation mass spectra. The selected spectra are accumulated to produce a secondary accumulation mass spectrum.

摘要： Tandem time-of-flight mass spectrometry method and apparatus permits an ion gate to be time set optimally at all times if the instrumental conditions are modified. Delayed extraction conditions for the mass-to-charge ratios of plural reference substances and optimum values of the time for which the ion gate is opened are measured and stored in a data table. Delayed extraction conditions and opening time of the ion gate which optimize the mass resolution at the mass-to-charge ratio of the desired precursor ions are found based on values stored in the table.

摘要： A tandem time-of-flight (TOF) mass spectrometer is offered whose first mass analyzer is a TOF mass spectrometer having a flight distance smaller than the flight distance sufficient to impart a desired mass resolution to the first mass analyzer. When a mass spectrum is measured with the first mass analyzer, a reflectron field is activated. When precursor ions are selected by the first mass analyzer, the reflectron field is deactivated to permit ions to pass through without being reflected.
