Abstract

The invention provides a mass spectrum system and a measurement method thereof. The mass spectrum system comprises an ion source subsystem, an ion accelerator subsystem, a high-energy analyzer subsystem and a particle identification and detector subsystem which are connected in sequence. The ion source subsystem comprises a sample injector component and a super-strong ionization ion source component connected with the sample injector component; the high-energy analyzer subsystem comprises an analyzer component connected with the ion accelerator subsystem and a beam measurement component connected with the analyzer component; and the detector subsystem comprises a thin film connected with the beam measurement component and a detector connected with the thin film. Interference of molecular ions is eliminated by adopting a super-strong ionization technology; the size of the atomic number Z can be detected by adopting a particle identification technology, so that the same amount of ectopic ions and the information of ions with different mass numbers but the same M/q, namely ZM/q information, are obtained, and finally, the real mass spectrum measurement is realized.

Description

technical field [0001] The invention relates to the technical field of a mass spectrometer, in particular to a mass spectrometer system and a measurement method thereof. Background technique [0002] Since the advent of the mass spectrometer (MS, Mass Spectrograph) in 1910, all MS (including magnetic mass spectrometry, quadrupole and time-of-flight, etc.) measurement results are mass-to-charge ratio (M / q) spectra, not real mass spectra . [0003] In a same M / q spectrum, it mainly includes four different ions, the first is the ion of the nuclide to be measured; the second is the isobaric ion of the nuclide to be measured; the third is the ion with the nuclide to be measured Measure the molecular ion with the same mass number of the nuclide; the fourth is an ion with a different mass number from the nuclide to be measured but the same M / q (both the mass number and the charge state are integer multiples of the nuclide to be measured). [0004] For example, the measurement of ...
