摘要： An ion source using a corona discharge for ionizing a sample at high efficient is provided. In the corona discharge generated at a tip end of a needle electrode by application of high voltage thereto, the direction in which the sample is introduced to the region of corona discharge and the direction in which ions are drawn out of the corona discharge region are substantially opposed to each other to improve the efficiency of ionization and to maintain a stable discharge for a long period of time.

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.

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.
