摘要： PROBLEM TO BE SOLVED: To ensure a high sensitivity despite low flow speed of a moving phase by providing a means to atomizing a solution containing a sample eluded from a capillary and a means to turn the produced liquid drops into finer particulates or gaseous form, shutting off the communication between the two means so that no gas will intrude from the outside, and providing an ion source to permit the two means to operate with the same heating device. SOLUTION: A sample introduced to a semi-micro liquid chromatograph 46 is passed through a Teflon tube 2 and a stainless steel capillary 3 together with a solvent as a moving phase and introduced to a heating part 26 of a metal block 36 which is heated to 150-250 deg.C by a cartridge heater 39. The sample 6 and the solvent atomized into the atmosphere in the heating part 26 are passed through a small hole in a plate 27 and sent to a corona discharge space accommodating a needle electrode 8 where a high voltage is impressed by a corona discharge power supply 7, and there ionization takes place. The produced ions are passed through a thin hole formed in the first electrode 10 and exhausted from an exhaust part 12 surrounded by the electrode 10 and a second electrode 11. The accelerated ions 9 are passed through a thin hole provided in the second electrode 11 and converged by an ion lens 15.

摘要： PROBLEM TO BE SOLVED: To ensure the high efficiency of ionization. SOLUTION: A quartz capillary 2 having an inner diameter of 0.1mm and an outer diameter of 0.2mm is connected to a sample liquid introduction part 1 formed out of a syringe pump or the like. In addition, the capillary 2 is made to penetrate an ion source body 6, so as to have the end thereof positioned within an orifice 3. Also, the center line of the orifice 3 and the center line of the capillary 2 are aligned with each other, and an injection gas feed part 4 is connected to the ion source body 6 via an injection gas introduction tube 5. Furthermore, a slope expanding externally from the inner side is formed in the orifice 3.

摘要： PROBLEM TO BE SOLVED: To provide an ion source capable of generating positive or negative ions at high efficiency by positioning an electrode near both ends of a spray capillary, applying voltage to a sample liquid and, then, spraying the liquid. SOLUTION: A sample liquid in an ion source is introduced from a flow passage 1 to a capillary 2. The end of the capillary 2 is inserted in an orifice 3 coaxially. Gases from a gas supply part 4 are introduced to an ion source body 6 via a gas introduction tube 5, and discharged outside from the orifice 3. This orifice is made of metal, and voltage is applied across the orifice 3 and a metal tube 8 from a power supply 7, thereby applying electric field to the liquid. The liquid, upon arrival at the end of the capillary 2, is sprayed on a gas flow having a speed approximately equal to sound speed. As a result, ions and fine and electrified liquid drops are generated in the atomized gases.

摘要： PURPOSE:To obtain a method for introducing a trace sample solution required for mass spectrometry using flow injection method. CONSTITUTION:A sample solution 21 is filled in a capillary tube 20 having one end coupled with an ion source 3. The capillary tube 20 is then held high, at the other end thus feeding the sample solution gravitationally to the ion source 3. Since a trace sample solution 21 can be introduced continuously into the ion source 3, even a dilute solution 21 can be subjected to mass spectrometry with high sensitivity.

摘要： PURPOSE:To detect the ion of a sample molecule in spray gas stably with high sensitivity by arranging a tubular spray gas guide on the tip of a spray capillary. CONSTITUTION:Sample solution separated by a liquid chromatograph(LC) 1 passes through piping 2, and is introduced to a spray capillary 4 of an ion source 3. Spray gas generated in the capillary 4 is introduced into a mass spectrometer 6 after being introduced into a spray gas guide 5 situated on the tip of the capillary 4, and mass spectrometry is carried out on an ion contained in the spray gas. An inside diameter of the gas guide 5 is made to coincide almost with an outside diameter of the capillary 4. In this constitution, the spray gas discharged from the tip of the capillary 4 is introduced highly densely into an ion intake port of the mass spectrometer by the gas guide 5 without being diffused spatially, and can be detected with high sensitivity. A capillary electrophoretic device is used in a capillary electrophoresis/mass spectrometer instead of the LC1 and the piping 2.

摘要： PURPOSE:To eliminate an energy loss due to friction by levitating the rotating part of an apparatus with the aid of the Meissner effect of a superconductor. CONSTITUTION:The surrounding part of the center shaft 1 of the rotating part of a rotating apparatus is constituted by a superconductor 2, and a magnet 3 is arranged so as to surround the periphery of the superconductor 2. Thus, a part of the superconductor 2 (the surrounding part of the center shaft 1 of the rotating part) levitates by the Meissner effect within the magnet 3, and an energy loss due to friction between the center shaft 1 and bearing of rotating part is eliminated completely. Also, in this case, one end of the center shaft 1 is provided with a metal conductor 4, and a rotary magnet 5 is provided so as to face the metal conductor 4, and is rotated so that the metal conductor 4 revolves to enable rotation of the center shaft 1 of the rotating part.

摘要： PURPOSE:To prevent incident primary ions from a complex deflection owing to the potential variation in the incidence, and from the variation of the incident angle, and to make the ions hit the sampling face with a good reproducible performance, by furnishing a metallic primary beam guide at the electric field variating area to the ion radiated portion. CONSTITUTION:To collect the secondary ions 6 radiated from a target 2 efficiently and to lead them to the analyzing portion, it is desired to make the target 2 in the ionizing room parallel to an electrode 4 which has a lead out slit, and to make the primary beams 1 project in at an angle about 20 deg. from the secondary ion radiating direction 6. In this case, since the primary particles pass through a lens 5 and the like to focus the secondary ions, they are deflected in the direction up and down. Therefore, a metallic guide 8 given with the same or equivalent potential to the secondary ion accelerating potential is furnished at the passage from the earth potential to a higher voltage portion, to reduce the deflection. The incident face to the guide portion is square to the incident direction of the primary ions as shown in the figure, to prevent the deflection in the incidence.

摘要： PURPOSE:To enable the connection of a mass spectrometer to a liquid chromatograph LC allowed to use a elution liquid containing salts, by making salts in the elution liquid containing salts settle by a chelate reagent. CONSTITUTION:An LC10 is made up of an elution liquid tank 1, a sample tank 2 and an LC column 3 and an interface 11 lets a chelate reagent to a post column 6 with a pump 4 from a chelate reagent tank 5 to make salts settle in an elution liquid. Then, an outflow liquid comprising the elution liquid and a sample passing through the IC column 3 and the post column 6 is atomized with an atomizer 7. Thus, the sample atomized is ionized with an ion source section 8 and is subjected to a mass analysis with a mass spectrometer section 9. This enables the connection of an LC10 allowed to use an elution liquid containing salts to a mass spectrometer 12 through an interface 11.

摘要： PURPOSE:To make a fine tube and a fine pore hard to generate clogging even if a salt-containing buffer solution is used as the carrier of a liquid chromatograph, by providing a washing mechanism to the salt precipitation area in the apparatus for connecting the mass analyser of the liquid chromatograph. CONSTITUTION:When a salt-containing buffer solution is used as the carrier of a liquid chromatrograph 1, the output from the liquid chromatograph 1 passes through a valve 4 and an interface 5 to be guided to a mass analyser 20 during usual measurement. When measurement is completed, a controller 21 changes over the three-way cock of a time valve 4 necessary for washing fine bore 6 so as to communicate a pump 3 and the fine bore 6 and operates the pump 3. By this mechanism, the salt solvent solution from a solution sump 2 is introduced into the fine bore 6 through the pump 3 and the valve 4 and the evaporated solvent is guided to the mass analyser 20 through a jet orifice 9 while dissolves the salt precipitated and adhered to the fine bore 6 and discharged from an excessive gas vent port 15.
