摘要： A mass spectrometer for efficiently ionizing a sample with less carry-over. The ratio of the amount of sample gas to that of a whole headspace gas is increased by decreasing the pressure inside of a sample vessel in which the sample is sealed thereby efficiently ionizing the sample.

摘要： A variation in an ionization efficiency and the amount of sample which is introduced into an ion trap is corrected and quantified. 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.
