Analysis device and analysis method

An analyzer, comprising:

• an authentication region including a face, to which an authentication target is to be brought closer;
• an authentication database configured to hold authentication data;
• a blowing region configured to send air flow along the authentication region, thus removing a sample attached to the authentication target;
• an introduction region configured to suck the sample removed from the authentication target;
• a sampling region having a conic condensation device, the sampling region being configured to condense and sample the sucked sample;
• a large intake unit provided above the condensation device;
• collection filter provided at a smell-radius part of the condensation device;
• a heating unit that heats the collection filter provided at the small-radius part of the condensation device;
• a small intake unit configured to continuously suck a sample from a rear face of the collection filter, the sample having been sampled to the collection filter and vaporized through the heating;
• an ion source configured to introduce the sucked sample 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 perform identification using both a determination result of presence or not of the detection target substance obtained by comparing a result of mass analysis of the sample at the mass analysis region with the mass spectrum data held at the data base unit, and a determination result of whether or not data on the authentication tar obtained in the authentication region agrees with the authentication data held in the authentication database.

An analyzer, comprising:

• a gate letting a subject pass therethrough;
• an identification region configured to detect approaching of the subject to the gate;
• a blowing region provided at the gate, the blowing region being configured to send air flow to the subject passing through the gate, thus removing a sample attached to the subject;
• an introduction region provided at a floor face or a side face of the gate, the introduction region being configured to suck the sample removed by the air flow sent by the blowing region;
• a sampling region having a conic condensation device, the sampling region being configured to condense and sample the sucked sample;
• a large intake unit provided above the condensation device;
• a collection filter provided at a small-radius part of the condensation device;
• a heating unit that heats the collection filter provided at the small-radius part of the condensation device;
• a small intake unit con ed to continuous suck a sample from a rear face of the collection filter, the sample having been sampled to the collection filter and vaporized through the heating;
• an ion source configured to introduce the sucked sample 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.

An analysis method, comprising:

• a step of acquiring authentication data from an approaching authentication target;
• a first comparison step of comparing the acquired authentication data with authentication data held in an authentication database;
• a step of removing a sample attached to the authentication target;
• a step of sucking the removed sample;
• a step of condensing and sampling the sucked sample to a surface of a heated collection filter by a principle of a cyclone;
• step of continuously sucking a sample vaporized through heating from a rear face of the collection filter, and ionizing the sample;
• a step of performing mass analysis of the ionized ions;
• a second comparison step of comparing a mass spectrum obtained as a result of the mass analysis with mass spectrum data held at a database, the mass spectrum data being derived from a detection target substance;
• and
• a step of performing identification using both a determination result of presence or not of a component substance of the detection target substance based on a result of the second comparison step, and a determination result of whether or not the acquired authentication data agrees with the authentication data held in the authentication database in the first comparison step.
