    Abstract: A portable mass spectrometer that is carried to a sampling site to conduct analysis incorporates measures against erroneous operation. To prevent erroneous operation, when a measurement sample cannot be accurately analyzed because of contamination in the measurement sample, a criterion for aborting the sample measurement is provided and mass spectrometer control maintenance is performed. When urine is measured, the mass spectrometer detects the substances contained in the urine and automatically determines whether the sample is urine. The mass spectrometer then automatically selects an analysis condition specific to urine samples to make a measurement. Also with respect to sweat and saliva, the mass spectrometer similarly selects a specific analysis condition. The mass spectrometer automatically determines whether a sample, which is an internal standard sample contained in a sample case, is being measured on a measurement-by-measurement basis and automatically displays any error, interrupts the measurement, or carries out other processing.

    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.
