ABSTRACT:
A mass spectrometer which comprises an ion source for ionizing a sample and a mass analyzing region for introducing the thus formed ions into a vacuum and mass analyzing the ions, the ion source being provided with a spray ion source comprising a heatable capillary working at least under the atmospheric pressure, the center axis of the capillary being aligned along the center of an aperture for withdrawing the ions and the tip end of the capillary being positioned close to the aperture ionizes a sample from a liquid chromatograph by both atmospheric pressure ionization mode and a thermospray ionization mode and mass analyze the ions, thereby obtaining more exact analytical information on the sample.
