    Abstract: A mass spectrometer device comprising an ion mobility separation device and a mass spectrometer that are coupled together. In order to achieve high efficiency, high throughput, and high sensitivity, the mass spectrometer is provided with: a first flow passageway 24 through which ions from an ion source 1 are introduced into the mass spectrometer 11 by passing through an ion mobility separation unit 2; a second flow passageway 21 through which the ions from the ion source are introduced into the mass spectrometer without passing through the ion mobility separation unit; and a switch means, such as shield units 4, 5, for switching between the first flow passageway 24 and the second flow passageway 21.

    Abstract: There is a tendency of the intensity and the shape of a spectrum to be measured transitioning with the passage of measured time, depending on the volatility and the reactivity of a component. A mass spectrometric system includes: a mass spectrometric unit that measures a specimen and outputs a mass spectrum; and an estimator that has an estimation rule on content information, the estimation rule being assigned to each component and each measurement time. The estimator estimates, based on a mass spectrum output from the mass spectrometric unit, content information on each component of a plurality of components that may be contained in the specimen in accordance with the estimation rule.

    Abstract: A first rod electrode set has a first center axis, into which ions and air current are introduced. A second rod electrode set has a second center axis at a distance from the first center axis, from which the ions are discharged. A power supply applies voltages to the first rod electrode set and the second rod electrode set. The first rod electrode set and the second rod electrode set have a region where the sets overlap each other in the longitudinal direction, and form a single multipole ion guide by being combined to each other in the region. Different offset DC voltages are applied to the first rod electrode set and the second rod electrode set, respectively, and a DC potential for moving the ions to the second rod electrode set in the region is formed, the ions having been guided by the first rod electrode set.

    Abstract: 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.
