In order to detach substances stably from an inspection object, an adhering substance collecting device includes: ejection openings configured to eject gas; a housing on which the ejection openings are provided; and supporting portions which are installed on a surface of the housing on which the ejection openings are provided, and have a prescribed height. The supporting portions include protruded portions formed on the housing. The supporting portions each have a cuboid shape, and are installed such that a distance therebetween becomes smaller toward a direction of a recovery opening that is configured to collect substances having been detached from an inspection object, from the gas.

Adhering substance collecting device and inspection system

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.
