摘要： An ion mobility spectrometer has a pair of electrodes (13A) and (13B) midway along the drift chamber (7). A high field is applied between the electrodes (13A) and (13B) sufficient to modify (e.g. fragment) ions in the region of the electrodes such that they move at a different rate towards the collector plate (8) . This is used to modify the time of flight of selected ions or ion clusters and enable identification of ambiguous peaks on the IMS spectrum.

摘要： An exact centroid spectrum with a mass number corrected is determined from a profile spectrum adjacent to a plurality of peaks. Regarding a profile spectrum determined by a mass spectrometer, overlapping with adjacent peaks occurs, and compounds having a plurality of peaks with different overlapping degrees is measured, a correction function is created from a relationship between an overlapping degrees with respect to the plurality of peaks and a shift of the mass number, and a centroid peak is corrected by the correction function when the profile spectrum is converted into the centroid spectrum.

摘要： A method and mass spectrometer system for trapping ions within an ion trap by increasing the flight path of ions therein. An ion beam is produced by external ion source and is directed to the ion trap which comprises at least one trapping electrode in proximity to an exit region of the ion beam from the ion trap. A retarding DC voltage is applied to the trapping electrode during ion accumulation time for creating a fringing reflection field and for retaining ions within the ion trap.

摘要： A standing electromagnetic wave haing nodes, penetrates through a gaseous jet of the mixture of the isotopes to be separated, while relative motion takes place between the wave and mixture in such a manner that the isotopes are prevented from dwelling in the vicinity of the wave nodes while the isotopes are traversed by the electromagnetic wave. By adjusting the frequency of the electromagnetic wave so that the individual isotopes of the mixture are selectively influenced differently as far as their dipole behavior is concerned, they can be segregated by the electric and/or magnetic field of the wave. Undesirable effects of such dwelling can also be reduced by the angularity at which the wave penetrates the gaseous jet.
