    摘要： 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.

    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.
