    Abstract: A fast method for determining molecular mass using mass spectrometry has the following steps: specifying a first adjusting value (M1) of the mass spectrometer, recording the associated signal amplitude (A1), specifying a second adjusting value (M2) which is different to the first, measuring the associated second signal amplitude (A2), specifying a third adjusting value (M3) which is different to the first (M1) and the second (M2) adjusting value, measuring the associated third signal amplitude (A3), determining a quadratic function containing the measured amplitude values as y-values and the specified adjusting values as x-values, determining the maximum of the quadratic function, wherein the searched adjusting value is determined from the x-value of the maximum.

    Abstract: A collector for use in removing metal ions from a plasma in a vacuum chamber includes a collector plate that is mounted inside the chamber and formed with an internal cooling channel. An injector introduces a dissociated salt into the chamber with a first throughput value, and it introduces a plasma including metal ions into the chamber with a lower second throughput value. A pump is used to pump a liquid coolant through the cooling channel to maintain the collector plate at a temperature that forms a portion of the salt as a protective layer on the collector plate, and causes the salt to thereafter deposit on the layer in a molten condition at a faster rate than evaporation therefrom to trap metal ions therein. The trapped metal ions are then removed with the molten salt from the chamber.

    Abstract: A multi-mass filter for separating particles according to their mass-charge ratio includes a chamber for receiving a multi-species plasma that includes particles therein having different mass-charge ratios (with M1 Mc3) and only the intermediate particles M2 are ejected into the second region (M2>Mc2). In another embodiment, the radial electrical field is increased outwardly from the axis to a radial distance a2 (r2) at a first rate. The electrical field is then increased radially outward between a2 (r2) and a radial distance a3 (r3) at a lower rate. This electric field configuration defines the first region between the axis and a2 (r2), and the second region between a2 (r2) and a3 (r3). The third region is located radially beyond the second region. Accordingly, with Mc2=er22B2/(8*(Vctr−V2)) and Mc3=e(r32−r22)B2/(8*V2), particles M1 are confined in the first region, while both particles M3 and M2 are ejected from the first region into the second region. The particles M2 are, however, confined in the second region and only the particles M3 are ejected from the second region into the third region.

    Abstract: In isotope mass spectrometry, there is the problem that in the case of very great frequency differences, the less frequent masses are swamped by the more frequent masses in the measurement result or that the corresponding measurement result is falsified. A correction device is proposed, which comprises a quadrupole mass filter with a voltage supply device which is controlled by the ion separation system and is designed in such a manner that the supply voltages of the quadrupole mass filter and thus its characteristic with respect to the mass quantity to be allowed through are switched over synchronously with the varying mass deflection setting of the ion separation system.

    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.
