    摘要: Objects of the present invention is to provide a quadrupole mass filter that can be fabricated at low cost and has a high transmission efficiency even under a high pressure (0.5 mTorr or more), and to provide a mass spectrometer or mass spectrometry method that reduces crosstalk in a wide mass range. Now, in a mass spectrometer, an ion separating unit is configured to include quadrupole rod electrodes that form a quadrupole radio-frequency electric field, electrodes that form a quadrupole electrostatic field, and a power supply that allows the voltage of the electrodes to form a quadrupole electrostatic field to change. In a collision cell configured to perform collision induced dissociation, harmonic potentials in a plurality of stages are produced to resonance excite ions in the axial direction, so that the ions obtain kinetic energy to move in the direction of the detector. This energy allows a time period to shorten for which ions stay in the collision cell.

    摘要: A mass spectrometer of reduced size and weight is provided which is capable to conduct highly accurate mass spectroscopy. The mass spectrometer includes an ion source adapted to ionize gas flowing in from outside in order to ionize a measurement sample and a mass spectroscopy section for separating the ionized measurement sample. The ion source has its interior reduced in pressure by differential pumping from the mass spectroscopy section and ionizes the gas when the interior pressure rises as it inhales the gas, and the mass spectroscopy section separates the ionized measurement sample when its interior pressure falls after inhale of the gas. The mass spectrometer may further include a restriction device for suppressing a flow rate of the gas the ion source inhales and an open/close device for opening and closing a flow of the gas the ion source inhales.

    摘要: A mass spectrometer that is switchable to operate as a linear trap or as a mass filter, and attaining both high ejection efficiency when operated as a linear trap and high mass resolving power when operated as a mass filter. A mass spectrometer includes an ion source for ionizing a sample, a linear trap quadrupole rod lens supplied with ionized ions, a trap electrode for forming a potential to trap the supplied ions between one end of the quadrupole lens and the other end, a control unit to regulate the trap lens voltage, and a mass analyzer or detector to detect ions ejected from the linear trap, and characterized in switching between an operation where the supplied ions are trapped in a section quadrupole rod lens and ejected by the controller unit regulating the trap electrode voltage; and an operation where ions are selective passed through according to their mass. The ejection efficiency when operated as an ion trap, and the mass resolving power when operated as a quadrupole mass filter are vastly improved compared to conventional methods.
