Abstract: In a conventional fine particle detection device that vaporizes fine particles attached to the object of examination by heating, processing capability decreases as the processing time elapses due to the influence of deposition of fine particles other than the object of examination, dirt/dust, a residue of the fine particles as the object of examination, or residual matter. A fine particle detection device according to the present invention includes: a vaporization device that vaporizes the fine particles trapped by a trap device by vaporization or decomposition; a first flow passageway in which a mixture of a component vaporized by the vaporization device and another component flows; a second flow passageway branching from the first flow passageway in a direction of inertial force acting on the other component; a third flow passageway branching from the first flow passageway in a direction different from the direction of the inertial force; and an analysis device that analyzes a component introduced into the third flow passageway.

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.

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.

Abstract: Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication target 2 are removed by air flow from a blowing region 5. The removed sample is sucked and is condensed and sampled at a sampling region 10, and ions of the sample are generated at an ion source 21 and are then subjected to mass analysis at a mass analysis region 23. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitor 27 displays a result thereof. Thereby, the detection target substance attached to the authentication target 2 can be detected continuously in real time, promptly and with a less error rate.

Abstract: 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.
