摘要： 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.

摘要： 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.

摘要： In order to implement a high-sensitivity mass spectrometry through an improvement in solvent removal efficiency during electrospray ionization and the like, an ionization device is provided with a light guide path 28 which guides light from a light source to sample microparticles generated by a micronization device to irradiate the microparticles. A closest distance d2 between a spatial area 34 in which the sample microparticles are present and a distal end 29 of the light guide path is greater than or equal to 0.1 mm and less than or equal to 20 mm. A closest distance d1 between an area of light irradiation 35 by the light guide path and any of a sample surface, a micronization device, and a sample holding unit that is the closest is greater than or equal to 0.01 mm and less than or equal to 10 mm.

摘要： 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.
