Abstract:
1. A mass spectrometer comprising: an ionization chamber which generates fragment-free ions to be detected from an introduced gas to be detected; a mass spectrometer chamber including a mass spectrometer which fractionates by mass the ions to be detected that are transported from said ionization chamber and which detects the ions; a probe which holds a liquid sample or a solid sample and causes the liquid sample or the solid sample to generate the gas to be detected upon heating by heating means; a sample evaporation chamber which is connected to said ionization chamber via a connecting pipe; and introduction means for introducing a predetermined gas from said probe to said ionization chamber to transport, to said ionization chamber, the gas to be detected that is generated at said probe, wherein said probe is arranged in said sample evaporation chamber, and said introduction means is connected to said sample evaporation chamber.
