摘要： PROBLEM TO BE SOLVED: To solve the problem that a conventional MS/MS method cannot compatibly attain throughput and precursor ion mass resolution.
SOLUTION: This mass spectrometer includes an ion trap for discharging ions in a specified mass range, a collision dissociation part for dissociating the ions discharged from the ion trap, and a mass spectrometric part for performing the mass spectrometry of the ions discharged form the collision dissociation part. It resonantly discharges the ions introduced and accumulated into the iron trap in a mass selective manner. It measures the precursor ions in the conditions that incident energy into the collision dissociation part is low, and acquires a set of the profile of the precursor ions at the mass axis of the ion trap part and the profile thereof at the mass spectrometric part. Then, it measures the precursor ions in the conditions that incident energy into the collision dissociation part is high, and replaces the profile at the mass axis of the mass spectrometric part with the profile of the precursor ions of the obtained two-dimensional mass spectrum at the mass axis of the iron trap part. In this method, m/z of each of the precursor ions and fragment ions can be determined with high mass resolution.

摘要： PROBLEM TO BE SOLVED: To make liquid-drop density that is taken into the mass spectroscope a correct value and reduce the noise in the sonic spray ion source and mass spectroscope. SOLUTION: The solution sample in the sample solution introduction part 1 is introduced into a capillary 2. The capillary 2 is installed in the ion source 6. The gas that is supplied from a gas supply part 4 is introduced into the ion source 6 by a gas tube 5 and flown along the outer circumference of the capillary 2 and discharged from the orifice 3 into the air. The gas flow touches the dispersing member 7 and is dispersed. The fine liquid-drops or ion that are generated in the air pass through a hole 8 of the dispersing member 7 and are taken into the mass spectrometer 11 from a thin hole 10 and analyzed for mass spectrometric analysis. Even in the cases where the flow rate of the sample solution is higher than the conventional sonic spray ion source and mass spectroscope, this can be used. By auto-tuning, the adjustment work of the user is reduced.

摘要： PROBLEM TO BE SOLVED: To enlarge the application range of a capillary electrophoresis mass spectrometer by making analyzable a neutral sample without electric charges in a solution and making usable various buffer solutions. SOLUTION: A sample solution separated by a capillary electrophoresis part 18 is atomized by an atomizing part 19, then heated and vaporized by a vaporizing part 20. The obtained sample molecules of a gas are ionized by a chemical ionizing part 21 having a corona discharge part through a protonation reaction or the like by a chemical reaction. The thus-produced ions related to the sample molecules are introduced from an ion introduction thin hole 10a to a vacuum chamber and analyzed by a mass spectrometric part 14 and an ion detector 15. Since the sample is ionized by the chemical ionization, even the sample without electric charges in the solution can be analyzed. Since a sensitivity to ionic substances is low, a buffer solution with salt added can be used.

摘要： PROBLEM TO BE SOLVED: To produce positive or negative ions with high efficiency, by installing an electrode near a spray capillary and by applying an electric field on liquid and by spraying the liquid, in a sonic spray ionization method. SOLUTION: This ion source is equipped with a capillary 2 for spraying liquid into the atmospheric air, and an orifice 3 installed by inserting a part near the head of the capillary 2 and formed so that gas will flow up to the head of the capillary 2 along the circumferential wall surface of the capillary 2. A gas flow velocity near the head of the capillary 2 is about a sound velocity, and a voltage is applied between the liquid in the capillary 2 and the orifice 3 or an electrode installed near the capillary 2. Hereby, the electric potential of the liquid can be set equally to the earth potential, and combination of a solution separation means with a liquid introduction part is easily realized. Also, the polarity of produced ions can be controlled according to the polarity of the voltage applied on the electrode. Besides, multi-charged ions of material having a large mass, such as a protein or the like, or the like can be produced with high efficiency and excellent repeatability.
