摘要： An ion trap/time-of-flight mass spectrometer, which can perform accurate mass measurement of a product ion based on MS/MS and MSn has an ion source for ionizing a sample, an ion trap capable of temporarily trapping ions, and a time-of-flight mass spectrometer. The ion source produces ions of the sample as a measurement target and ions of a reference sample each having a known mass value. A precursor ion is selected from among the ions of the measurement target sample, and the selected precursor ion is excited and fragmented in the ion trap to produce a product ion. The reference sample ions are introduced to and trapped in the ion trap. The trapped product ion and reference sample ions are expelled out of the ion trap and introduced to the time-of-flight mass spectrometer, thereby obtaining a mass spectrum.

摘要： A nebulized jet from a nebulizer is subjected to mechanical agitation and stirring to render the mists uniform and fine, then the droplets of the mists thus rendered uniform and fine are ionized. By accelerative collision of the resulting ions in a medium pressure chamber it is made possible to effect desolvation efficiently. Consequently, chemical noises caused by cluster ions can be greatly diminished and it is possible to attain high sensitive measurement of a sample in atmospheric pressure ionizations LC/MS.

摘要： An eluant is supplied to an analyzer column, a sample solution is supplied through a sample inlet. The analyzer column separates the components of the sample solution. The separated components are eluted by the analyzer column, the eluted components are detected by an eluted component detector, the results of detection provided by the eluted component detector is processed by a data processor to produce a liquid chromatogram having peaks indicating the components of the sample. The components of the sample is supplied through a capillary pipe to an ion source and the ion source ionizes the components of the sample. A mass spectrometer subjects the ions produced by the ion source to mass analysis, an ion detector detects the ions included in a mass spectrum to produce an ion chromatogram having peaks. A time difference between the chromatograms is determined beforehand through an experiment using a standard sample, and the liquid chromatogram is shifted on its time axis by the time difference.
