摘要： An ion source using a corona discharge for ionizing a sample at high efficient is provided. In the corona discharge generated at a tip end of a needle electrode by application of high voltage thereto, the direction in which the sample is introduced to the region of corona discharge and the direction in which ions are drawn out of the corona discharge region are substantially opposed to each other to improve the efficiency of ionization and to maintain a stable discharge for a long period of time.

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.

摘要： In an analytical apparatus, an ion trap mass spectrometer and a detector for detecting ions separated in the mass spectrometer are installed in different chambers. Ions generated from an ion source and passing through two differential pumping chambers into a third chamber containing the detector are deflected from their initial trajectory into the mass spectrometer in a fourth chamber for separation. In a first embodiment, the separated ions are returned along the same path into the detector in the third chamber. According to a second embodiment, the detector is located along the path of ion travel beyond the mass spectrometer, and the separated ions pass through a second orifice in the mass spectrometer and into the detector in the third chamber.
