ANALYSIS DEVICE AND ANALYSIS METHOD

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.

主权项

1. An analyzer, comprising:
a blowing region configured to remove a sample attached to a target; an introduction region configured to suck the sample removed from the target; a sampling region configured to condense and sample the sucked sample; an ion source configured to introduce the sample from the sampling region for ionization; a mass analysis region configured to perform mass analysis of ions generated at the ion source; a data processor configured to control the ion source and the mass analysis region; a database unit configured to hold mass spectrum data derived from a detection target substance; and an identification region configured to compare a result of mass analysis of the sample at the mass analysis region with the mass spectrum data held at the data base unit, thus determining presence or not of the detection target substance.
