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: 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: An ion mobility separation device includes: an ion source that generates an ion; a pair of flat-plate electrodes having an introduction opening and a discharge opening for the ion generated by the ion source; a pump for causing the ion introduced via the introduction opening of the pair of flat-plate electrodes to travel toward the discharge opening; a voltage control unit that applies an asymmetric time-varying voltage and a direct-current voltage to the pair of flat-plate electrodes; a plurality of detectors disposed in a direction orthogonal to both an ion travel direction due to the pump and an applied direction of the asymmetric time-varying voltage; and a signal processing unit that processes a signal detected by the plurality of detectors. The voltage control unit performs a total transmission measurement involving application of the voltages to the pair of flat-plate electrodes so as to generate equal fields at least at two different points in the direction orthogonal to both the ion travel direction due to the pump and the applied direction of the asymmetric time-varying voltage. Compared to conventional technology, both high accuracy and high throughput are achieved in an asymmetric field application-type ion mobility separation device.
