    Abstract: A mass spectrometer having a resolution improved by introducing ions into a mass spectrometry part with a high efficiency is provided with a small-sized, simple configuration. The mass spectrometer includes an opening/closing mechanism provided between a sample introducing piping part for introducing a sample into the mass spectrometry part and the mass spectrometry part to conduct gas introduction intermittently and control sample passage. The mass spectrometer further includes a pump mechanism to evacuate a high pressure side of the sample introducing piping part, that is, an opposite side of the opening/closing mechanism to the mass spectrometry part to have a pressure in a range of 100 to 10,000 Pa.

    Abstract: 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.

    Abstract: The quantitative accuracy of analysis is improved without reducing the dynamic range for measurement of concentrations by performing stable ionization through electrospray or the like which repeats sampling and ionization using a movable probe electrode.A voltage is applied from a high-voltage power source 4 to a sample transport electrode 7 having a plurality of probe electrodes 1 and a driving section 3 drives the sample transport electrode 7 to rotate. The plurality of probe electrodes 1, to which a sample solution 5 is adhered, are sequentially transported to an inlet 21 of a mass spectrometer 20, thus electrospray ionization is continuously performed.
