    摘要: A gas monitoring apparatus includes a sample introducing portion, a measurement portion, an ionization portion, a mass analysis portion, a data processing portion and a display. The sample introducing portion introduces a sample gas including an object material to be measured. The measurement portion measures a concentration of a predetermined coexisting material, which coexists with the object material in the sample gas. The ionization portion ionizes the sample gas. The mass analysis portion analyzes mass of an ion produced by the ionization portion. The data processing portion analyzes signals detected by the mass analysis portion to calculate a concentration of the object material. And the display displays results of analysis conducted by the data processing portion. The data processing portion includes an adjustment portion which adjusts the concentration of the object material according to the concentration of the predetermined coexisting material.

    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.

    摘要: There was previously no monitoring method and monitoring apparatus which could measure dioxins at ppt levels and dioxin precursors at ppb levels with high sensitivity. According to this invention, organic and inorganic compounds containing highly electronegative elements are selectively ionized by atmospheric pressure chemical ionization, the ions produced are detected by a mass spectrometer, and their amount is measured. As a result, interfering substances such as nitrogen, air, hydrocarbons and carbon dioxide which are the main components of flue gas are eliminated, and dioxins or organochlorine compounds such as dioxin precursors can be selectively monitored.
