An object of the present invention is to provide an apparatus for detecting organic trace components such as PCBs in waste water. Kind Code: A1 A solvent separating means for removing a solvent from a water-collected sample, a sample introducing means for introducing a sample from which a solvent has been separated into a vacuum chamber, and a sample introduced into an ionization section. Means 18 for ionizing with a laser beam 17, an accelerating unit 20 for accelerating the ionized molecules 19, a reflector 21 for reflecting the accelerated ion molecules 19, and an ion detector for detecting the reflected ion molecules 19 And a time-of-flight mass spectrometer 23 having the same.
