Device and method for detecting trace amounts of organic components |
摘要 |
The present invention provides an apparatus for detecting an organic trace component, and the detection apparatus is employed for detecting an organic halogenated substance contained in a gas. The detection apparatus includes a capillary column (54) (sample introduction means) for continuously introducing a collected sample (51) in the form of a leakage molecular beam (53) into a vacuum chamber (52); laser irradiation means (66) for irradiating the leakage molecular beam (53) with a laser beam (55) to thereby perform ionization; a convergence section (56) for converging molecules ionized through laser irradiation, the section including a plurality of ion electrodes; an ion trap (57) for selectively trapping the thus-converged molecules; and a time-of-flight mass spectrometer (60) including an ion detector (59) for detecting ions which are emitted at predetermined intervals and reflected by a reflectron (58).
