摘要： A spinning cell device is described for fast and convenient standardization and analysis of constituents and isotopes in solid samples by laser ablation inductively coupled plasma (LA-ICP) spectrometry. The method and apparatus for performing the method require the sample under test and a standard to be spun during ablation allowing the quasi-simultaneous ablation of both materials. The aerosols resulting from the ablation of sample and standard are mixed in the ablation cell allowing quantification of the ablated metals by the method of standard addition or isotope dilution. The relative proportion of standard verses sample ablated can be changed by altering the trajectory of the laser beam. The ablated aerosol is swept into an inductively coupled plasma by a carrier gas and analyzed by mass spectrometry.

摘要： After an analysis condition table for measuring each compound is automatically generated in accordance with a compound table, the loop time is calculated for each measurement section for which the overlapping of measurement events differs. If the loop time exceeds a specified value in a given measurement section of a given compound, the event with the earliest end time and the event with the latest start time are extracted from among the overlapping measurement events, and the intermediate time between the end time and the start time is found to adjust the length of each measurement event. By repeating this process, a parameter in the analysis condition table is corrected so that the loop time becomes equal to or less than the specified value.

摘要： A mass spectrometer is disclosed comprising a first storage ion trap arranged upstream of a high performance analytical ion trap. According to an embodiment ions are simultaneously scanned from both the first and second ion trap. At any instant in time the quantity of charge present within the second ion trap is limited or restricted so that the second ion trap does not suffer from space charge saturation effects and hence the performance of the second ion trap is not degraded.

摘要： An object of the present invention is to provide means for solving troubles. Examples of the troubles include sensitivity degradation and resolution degradation of a mass spectrometer, which are caused by an axis deviation of a component, particularly at least one orifice located between an ion source and a detector, to decrease the number of ions reaching the detector, and a variation in performance caused by exchange of components such as the orifice.For example, the invention has the following configuration in order to solve the troubles. A mass spectrometer includes: an ion source; a detector that detects an ion; an orifice and a mass separator that are disposed between the ion source and the detector; and an axis adjusting mechanism that adjusts axis positions of the orifice and/or the mass separator such that an opening of the orifice and/or an incident port of the mass separator is disposed on a line connecting the ion source and an incident port of the detector.

摘要： When an SIM measurement for ions originating from a target component separated by a chromatograph is performed, the measurement is performed while the mass-resolving power is switched among a plurality of levels of resolving power, with the mass-to-charge ratio fixed at a target value (S2), and an extracted ion chromatogram is created based on each of data obtained corresponding to respective mass-resolving powers (S3). After the extracted ion chromatograms are obtained, an S/N ratio is calculated for a peak of the target component on each of the chromatograms (S4), and a mass-resolving power which yields the highest S/N ratio is selected (S5). The selected mass-resolving power is set as the mass-resolving power in the subsequent measurements of the same target component in the same kind of sample (S6), and the quantitative determination of the target component is performed using the extracted ion chromatogram obtained with the selected mass-resolving power (S7).

摘要： A mass spectrometer is disclosed comprising a quadrupole rod set ion trap wherein a potential field is created at the exit of the ion trap which decreases with increasing radius in one radial direction. Ions within the ion trap are mass selectively excited in a radial direction. Ions which have been excited in the radial direction experience a potential field which no longer confines the ions axially within the ion trap but which instead acts to extract the ions and hence causes the ions to be ejected axially from the ion trap.
