摘要： In a mass spectrometer utilizing an atmospheric pressure ion source, the amount of un-vaporized droplets that reach a mass spectrometric section is reduced. A mass spectrometer comprises: an ionization section for ionizing a sample at substantially atmospheric pressure; a first and a second intermediate pressure section in which the pressure is maintained lower than the pressure in said ionization section; a high vacuum section in which the pressure is maintained lower than the pressure in said intermediate pressure section and in which a mass spectrometric means for subjecting ions to mass spectrometry is disposed; a first pore electrode disposed between said ionization section and said first intermediate pressure section; an intermediate pore electrode disposed between said first intermediate pressure section and said second intermediate pressure section; and a second pore electrode disposed between said second intermediate pressure section and said high vacuum section. A first converging electrode is provided in the first intermediate pressure section, the first converging electrode having an opening towards the first pore electrode and another opening towards the intermediate pore electrode. The opening towards the first pore electrode has a larger diameter than the opening towards the intermediate pore electrode, such that the first converging electrode has a tapered shape.

摘要： An “ion trap-TOF/MS” capable of calibrating the observed mass for each of an ion trap and a TOF. In the ion trap-TOF/MS, sample ions having known mass numbers and ionized by an ion source are trapped within an ion trap. Auxiliary AC voltages having a frequency component ω are applied to the end cap electrodes of the ion trap to expel unwanted ions out of the ion trap. A measurement process is carried out by applying DC voltages to the ring electrode and the end cap electrodes to expel an ion remaining within the ion trap, and measuring the mass number of the expelled ion by the time-of-flight mass spectrometer. The measurement process is repeated while changing the frequency component ω, and the ion signal intensity measured by the time-of-flight mass spectrometer is compared with a previously stored threshold, thereby making calibration of the frequency component ω for the ion having the known mass number. Thus, the calibrating of the observed mass can be realized for each of the ion trap and the TOF.

摘要： Disclosed is an ion trap mass spectrometer improved to obtain a high sensitivity without the lowering of resolution. By fitting a mesh electrode to an aperture (an ion sampling aperture or an ion extracting aperture) made in endcap electrodes constituting an ion trap mass analysis region, a radio frequency electric field in the mass analysis region is not disturbed even if the diameter of the aperture is set to a large value to heighten ion transmission efficiency. By fitting a shield electrode for preventing collision of ions with an insulated ring constituting an outer wall of the mass analysis region, charging up of the insulated ring is prevented to improve stability of detection signals. Furthermore, by arranging a shield member for shielding stray charged particles detouring through the circumference of the mass analysis region to approach an ion detector, generation of noises based on these stray charged particles is prevented.
