摘要： A mass spectrometer capable of measuring under switching two ion sources at different pressure levels in which a sample gas separated by GC column is branched, and separately introduced to a first ion source (for example, APCI ion source) and a second ion source (for example, EI ion source) at a pressure level lower than that of the first ion source respectively. Preferably, the flow rate of the sample gas introduced to the APCI ion source is made more than the flow rate of the sample gas introduced to the EI ion source, so that the pressure for each of the ion sources can be maintained and analysis can be conducted by each ionization at a good balance in view of the sensitivity.
