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 targetare removed by air flow from a blowing region. The removed sample is sucked and is condensed and sampled at a sampling region, and ions of the sample are generated at an ion sourceand are then subjected to mass analysis at a mass analysis region. 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 monitordisplays a result thereof. Thereby, the detection target substance attached to the authentication targetcan be detected continuously in real time, promptly and with a less error rate.
