摘要： In a quadrupole ion store (QUISTOR), a sample is analyzed by increasing themplitude of the harmonic, or "secular", oscillations of selected stably trapped ions so that they leave the trapping field. In a preferred embodiment, deviations from the ideal electrode geometry are incorporated into the QUISTOR to produce resonance phenomena between the r and z secular oscillations, thereby increasing the amplitude of oscillations in the z direction.

摘要： The measuring process for generating mass spectra using a sequentially-scanned quadrupole ion trap mass spectrometer, is improved by controlling the measurement of the ion packages ejected from the ion trap so that measurement takes place starting at the anticipated exit times of the ion packages and measurement continues only as far as possible for a time duration corresponding to the length of the ion packages. Measuring only during ion package ejection enables a measurement for the total number of ejected ions having a selected mass to be obtained by means of digital addition of the individual package measurements. Subsequent processing of the data can be carried out with practically only the fluctuations of normal ion counting statistics.

摘要： For mass-spectroscopic examinations of gas mixtures a mass spectrometer is used which comprises a quistor in which ions of the gas mixture whose charge-to-mass ratio is located in a predetermined range are stored by generating an electromagnetic field. By varying the field parameters, the ions are forced successively to leave the ion trap. The intensity of the ion flow leaving the ion trap is measured as a function of the variation of the field parameters. For improving the resolution, one uses a quistor of the type where the distance-related ratio Q of the radii of the inscribed vertex circles of the electrodes comply with the condition Q.ltoreq.3.990, wherein ##EQU1## R.sub.e being the radius of the cross-section of the vertex of the end electrodes (3,5);R.sub.r being the radius of the cross-section of the vertex of the annular electrode (4);z.sub.o being the distance between the vertex of each end electrode (3,5) and the center of the quistor; andr.sub.o being the distance between the vertex of the annular electrode (4) and the center of the quistor.

摘要： A method for the measurement of mass spectra by three dimensional quadrup fields (QUISTORs) is presented, in which the ions are mass-to-charge selectively ejected by a selected nonlinear resonance effect in an inharmonic QUISTOR. In order to enhance scan speed and mass resolution, the ejection of a single kind of ions can be confined to a very small time interval, either by the generation of ions within a small volume outside the field center, or by an excitation of the secular amplitudes by an additional RF voltage across the end electrodes, shortly before the ions encounter the sum resonance condition. An instrument for this method is described.

摘要： The invention relates to a device and a method for producing, from any previously configured ion beams, precisely localized small packages of ions which all fly at the same velocity. The invention consists of damping the ions in a damping-gas filled series of apertured diaphragms (which are firstly subjected alternately to the two phases of an RF voltage and secondly to a multiphase low-frequency travelling field voltage) into the axis of the apertured diaphragm arrangement and packaging the ions in bundles which are propelled axially at the same velocity for ions of different specific masses. These ion packages, which are restricted both in an axial and a radial direction, can be used to advantage for injection into different types of mass spectrometer, both storage ion-trap mass spectrometers, such as cyclotron resonance mass spectrometers or quadrupole ion traps and, especially, for time-of-flight mass spectrometers with orthogonal injection. The arrangement of a damping-gas filled series of apertured diaphragms can also be used for ion fragmentation.

摘要： The invention relates to high performance ion traps used as mass spectrometers which in spite of a variable thermal load require a high constancy of the mass scale calibrated in. Ion traps consist at least of one ring electrode, two end cap electrodes, and suitable fixing elements which determine the distance between the electrodes. When exposed to a thermal load, the parts of the ion trap are subject to thermal expansion, which leads to a change in field intensities even if the applied RF voltage is constant, and thus to an apparant shift of masses. The invention consists of selecting the thermal expansion of the ion trap parts in such a way that when a constant RF voltage is applied, the field intensity within the trap remains constant by first approximation, in spite of the altering geometric form and expansion with changing operating temperature. In this way, displacement of the mass scale is avoided. To compensate an unavoidable thermal expansion .DELTA.r.sub.0 of the ring electrode with an inscribed radius r.sub.0 by a ratio .DELTA.r.sub.0 /r.sub.0, the distance z.sub.0 of the end cap poles from the center of the trap must become smaller by the proportional ratio .DELTA.z.sub.0 /z.sub.0 =-.DELTA.r.sub.0 /r.sub.0. This compensation can be achieved by a suitable design with suitably selected expansion coefficients for the ion trap electrode material and the material of the fixing elements.
