Abstract: A mass spectrometry system includes a double-focusing magnetic sector mass spectrometer and a time-of-flight spectrometer arranged in parallel. The spectrometers share a common means for exciting ions from a sample, and a common transfer optics system. An interleaved control system for the two spectrometers, is arranged also to control a sampling handling arrangement dependent on the output of the time-of-flight spectrometer, so as to enable the double-focusing magnetic sector mass spectrometer to analyze a region of interest on a sample.

Abstract: A portable mass spectrometer is described having one or more electrostatic focusing sectors and a magnetic focusing sector, all of which are positioned inside a vacuum chamber, and all of which may be adjusted via adjustment means accessible from outside the vacuum chamber. Mounting of the magnetic sector entirely within the vacuum chamber permits smaller magnets to be used, thus permitting reductions in both weight and bulk.

Abstract: Detection of unknown daughter ions using a mass spectrometer in which two mass spectrometric units are coupled together. The spectrometric unit in the front stage has either an electric field or superimposed fields. The spectrometric unit in the rear stage has superimposed fields. The voltage Vdx.sub.2 necessary to produce the electric field in the front stage and the voltage Vdx.sub.1 necessary to produce the electric field of the superimposed fields in the rear stage when daughter ions having known mass and energy are detected are found. Further, the voltage Vdx.sub.2 ' necessary to produce the electric field in the front stage and the voltage Vdx.sub.1 ' necessary to produce the electric field of the superimposed fields in the rear stage when unknown ions are detected are found. Both the mass and the energy of the unknown ions can be determined from these four voltages.

Abstract: Between the electrostatic sector (SE 23) and the magnetic sector (SM 30) of a mass spectrometer, there is provided a quadrupole (QP 26) which applies parallel beams to the magnetic sector whose inclination depends on the energy dispersion of the particles. A slotted lens (LF 27) corrects the divergence of the quadrupole in the perpendicular plane. A suitable relationship between the angle of the inlet face of the magnetic sector (SM 30) and the deflection angle provided thereby ensures that the second order aperture aberrations of the magnetic sector are corrected. The chromatic aberrations may be corrected by means of a hexapole (HP 25) centered on the focus of the quadrupole (QP 26). Another hexapole (HP 22) placed upstream from the electrostatic sector (SE 23) level with a constriction in vertical section of the particle beam serves to correct second order aperture aberrations related to the electrostatic sector (SE 23).

Abstract: A mass spectrometer and process for using same comprises an ion source, a first field, a second field and a field-free region between the first and second fields. Parent ions are mass-selected by said first field and daughter ions are formed in the field-free region by ion dissociation or ion fragmentation. The daughter ions are dispersed by the second field. Superimposed electric and magnetic fields are used as the second field, the intensity of said magnetic field being changed from a first stage to a second stage and the intensity of said electric field being swept under both stages. Both energy and mass of the daughter ions can be measured by this mass spectrometer.

Abstract: Time of flight mass spectrometry techniques are simultaneously combined with path-bending spatial dispersion in magnetic- or electric-sector mass spectrometers to improve the mass resolution or, with an ion fragmentation region, to rapidly obtain multidimensional mass spectral data previously only obtainable by tandem mass spectrometry. The instrumentation generates data defining relationships between parent ions and daughter ions produced by fragmentation, metastable or induced, data to differentiate stable from metastable ions, and data to improve mass resolution. The subject time-resolved mass spectrometers can be combined with chromatography apparatus to obtain multidimensional MS/MS-type data during the relatively short duration of a single chromatographic peak.

Abstract: A double focusing mass spectrometer having a diverging electrostatic field, a converging electrostatic field and a converging magnetic field. The two electrostatic fields are connected with each other without substantial free space therebetween. The ion beam passes through the electrostatic fields coming to an intermediate focus point adjacent to the ion exit boundary of said converging electrostatic field. The beam then passes through the magnetic field to satisfy the double focusing condition in combination with the electrostatic field. Very small image magnification and aberration free focusing are obtained by this mass spectrometer.
