PROBLEM TO BE SOLVED: To reduce the number of metastable state atoms (molecules) of a carrier gas in a mass spectrometer, and also reduce a noise in a mass analysis. SOLUTION: A method for reducing noise in mass analysis includes: a step of ionizing a sample so as to generate ions of a specimen within the sample in the mass spectrometer; a step of separating the generated ions by a mass-charge ratio; a step of detecting the separated ions by a detector; and a step of introducing the gas in which the metastable state atoms (molecules) are reduced.
