  • Patent number: 10955401
    Abstract: In order to suppress malfunctions even when using a reagent (chemical for reagent) corresponding to a hazardous substance, the present invention has an analyzing unit in which a chemical for reagent, having added thereto an indicator that is different from a hazardous material that is a detection target, is used to calibrate on the basis of the detection target included in the chemical for reagent, and which performs mass spectrometry. When a peak corresponding to the indicator is not included and a peak corresponding to the detection target material is included in the spectrum that is the analysis result of the analyzing unit, the detection target is determined to be included.

  • Patent number: 9261437
    Abstract: Sample fine particles attached to an inspection object are identified simply and with high accuracy, and an increase in operation rate and a decrease in device size are achieved. The inspection object is transported into a sampling chamber defined by a pair of side walls and an upper wall enclosing a part of a transport route of a transport unit. The inspection object is sprayed with compressed gas from an air nozzle, the peeled sample fine particles are aspirated into a collector, and the sample fine particles are separated from the aspirated gas for analysis. The air nozzle is disposed on one of the side walls defining the sampling chamber. The collector is disposed under the other side wall as a container independent from the sampling chamber.
