    摘要: An analyzer carrying out analysis with a high degree of qualitative accuracy by separating impurities which hinder the analysis while analyzing in real time. An introducing tube is branched with one branched tube directly leading to an ion source for real time analysis. The other branched tube leads to the ion source so as to introduce the sample gas into the ion source at a later time. When a result of the real time analysis shows that a spectrum pattern on a MS spectrum is changed and an increase in the concentration of an impurity is observed, the introducing path for the sample gas is changed so that the sample gas is introduced into the ion source after the impurity is separated at the separation part.

    摘要: In a mass spectrometer having ion sources capable of switching between atmospheric pressure chemical ionization and electron impact ionization, a first gas chromatography device capable of separating a sample to meet a condition suitable for atmospheric pressure chemical ionization measurement is connected to upstream of an atmospheric pressure chemical ionization ion source. Part of the sample separated by the first gas chromatography device is introduced to a second gas chromatography device by distributing a flow channel. In the second gas chromatography device, a target substance and background ingredients contained in the sample are further separated and are introduced to an electron impact ionization ion source. By separating the target substance from the background ingredients, an electron impact ionization spectrum of the target substance is obtained without an effect of the background ingredients.
