  • Chemical for test used in hazardous substance sensing device, hazardous substance sensing device, and hazardous substance sensing method
    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.
    Type: Grant
