The invention relates to the field of gas analysis and analysis of volatile organic substances, is intended for the generation of ions with soft ionization and can be used as an ion source in gas chromatographs (GC) with a mass spectrometric detector and other analytical instruments. A mass spectrometer with the said ion source and a method of ionization using the mass spectrometer are also described. The technical result consists in simplifying the design, reducing the mass and dimensions of the mass spectrometer and the ion source, ensuring controlled fragmentation of molecules, including eliminating unwanted fragmentation of molecules during the ionization process, increasing the sensitivity of the analysis of molecules with the subsequent possibility of easier decoding of mass spectral information, simplification installation and use of the ion source without changing the design of the mass spectrometer, providing a higher signal-to-noise ratio.
An ion source of a mass spectrometer containing a vacuum chamber of the mass spectrometer, a channel supplying the analyzed material to the vacuum chamber of the mass spectrometer, a means for forming a molecular beam from the analyzed material coming through the channel and a means for ionization of the formed molecular beam installed in the vacuum chamber, characterized in that the means for forming a molecular beam is made in the form of a capillary assembly consisting of at least two capillaries, connected to a channel supplying the analyzed material into the vacuum chamber of the mass spectrometer, and located between the said supply channel and the ionization means.
