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

An object of the invention is to improve uniformity of a standard sample used for evaluating a gas flow type analysis system. The invention includes weighing a background into a container; adding a sample solution to the background; drying the sample solution; adding a solvent that can dissolve the sample into the container; and drying the solvent added to the container. The invention is also characterized in that the solvent is an organic solvent, in particular, acetone.

Method for preparing standard sample for gas flow type analysis 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.

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.
