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.
