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.

Abstract: Provided is a mass spectrometer capable of easy exchange of a measurement sample and suppressing a carryover. The mass spectrometer includes a mass spectrometry section, an ion source the internal pressure of which is reduced by a differential pumping from the mass spectrometry section and the ion source ionizes the sample gas, a sample container in which the sample gas is generated by vaporizing the measurement sample, a thin pipe that introduces the sample gas generated in the sample container into the ion source, an elastic tube of openable and closable that connects the sample container and the thin pipe, a pair of weirs that closes or opens the elastic tube so as to sandwich the elastic tube, and a cartridge that integrates the sample container, the thin pipe, and the elastic tube, and is detachable in a lump from a main body of the mass spectrometer.
