PROBLEM TO BE SOLVED: To provide a pyrolytic mass spectrometry technique which can spectrometry a hardly volatile organic minute foreign matter of severalμm becoming the bad cause of a device or the like with high sensitivity. SOLUTION: In mass spectrometry technique for introducing the sample gasified by a heating probe 2 into an ion source 4 and separating the ionized sample at each mass/charge ratio to detect the same, the heating probe 2 is covered with a cylindrical gas trap mechanism 3 and the gasified sample is efficiently guided to the ion source 4 by the gas trap mechanism 3 to allow even a sample component, which is conventionally diffused to be wasted, to contribute to spectrometry. Thereby, mass spectrometry of a good S/N ratio is performed with sensitivity higher than before. COPYRIGHT: (C)2011,JPO&INPIT
