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 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.

Ions of an internal standard and ions of a sample are trapped in the ion trap at the same time, and a concentration of the sample is quantified according to an intensity of the ions of the internal standard which are mass-selectively ejected, and an intensity of fragment ions of the sample.

摘要： The present invention relates to an ion trap with a large trap capacity. A mass spectrometer comprises a first linear ion trap that performs mass selective ejection, and a second linear ion trap that accumulates and then mass selectively ejects ions ejected from the first linear ion trap. Directions of resonant excitation of ions of the first linear ion trap and of the second linear ion trap are orthogonal. Compared to conventional art, sensitivity is significantly improved.

摘要： A mass spectrometer introducing ions produced at an ion source, and including quadrupole rods which have an inlet and an outlet and to which a radio-frequency voltage is applied, the mass spectrometer, i.e., a mass spectrometry device implemented by a linear trap which exhibits high ejection efficiency, high mass resolution, and low ejection energy, executes the following steps: Trapping at least part of the ions by a trap potential generated on the central axis of a quadrupole field, oscillating part of the trapped ions in an intermediate direction between the mutually-adjacent quadrupole rods, ejecting the oscillated ions by an extraction field, and detecting the ejected ions or introducing the ejected ions into another detection process.
