  Specifically, when the identification information of the person 9 is acquired by the identification information acquisition machine, the air of the air shower 21 is ejected for a predetermined time, and the person 9 adheres to the person 9 by passing through the air shower 21 during that time. The sample is blown off. Note that the air shower 21 only needs to be able to blow off the sample by the air flow, and it is not necessary to purify the air ejected from the air ejection port with a filter or the like.

The suction port 23 is a plurality of holes provided in a mesh shape on the floor 15, and is connected to one flow path 32 under the floor 15.
The trap filter 25 is disposed in a flow path 32 below the floor 15 and includes a plate-shaped metal filter 29 and an adsorbent 31 attached on the metal filter 29 as shown in FIG. .

  The metal filter 29 is, for example, a stainless steel, copper, or aluminum member having a thickness of about 50 to 500 μ (for example, about 100 μ). In the metal filter 29, holes having a diameter of about 1 μ to 1 mm penetrating in the thickness direction are provided in a mesh shape over the entire surface so that air can pass therethrough.

  The adsorbent 31 is, for example, a fiber member having a thickness of about several tens to 100 μm (for example, 100 μm), and can capture particles having a diameter of about 1 μm. Examples of the adsorbent 31 include fluororesin fibers (PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxyalkane), FEP (tetrafluoroethylene-hexafluoropropylene copolymer), PDVF (polyvinylidene fluoride)), and the like. Examples thereof include carbon fiber and glass fiber.

Note that the differential exhaust pipe 41 has a flow passage cross-sectional area of the flow path on the vaporization vessel 11 side (that is, the upstream flow path) such that the flow path on the differential exhaust pump 43 side (that is, the downstream flow path). It is desirable that it be formed smaller than the flow path cross-sectional area. By doing in this way, even if the pressure inside the flow path on the differential exhaust pump 43 side is lowered, it is possible to easily maintain a pressure difference from the inside of the vaporization container 11 under atmospheric pressure conditions.

  Further, the differential exhaust pipe 41 is provided with a pipe heater 42 around the pipe so that heat is transmitted to the inner wall of the differential exhaust pipe 41 so that the entire inner wall of the differential exhaust pipe 41 is heated. ing.

The differential exhaust pipe 41 may be formed of quartz, or the inner wall of the differential exhaust pipe 41 may be covered with quartz. By doing so, it is possible to prevent the substance from adhering to and staying on the inner wall of the differential exhaust pipe 41.

  The differential exhaust pump 43 includes an intake port and an exhaust port (not shown), and the intake port is connected to the downstream end of the differential exhaust pipe 41 so as to be able to flow therethrough. Further, the differential exhaust pump 43 exhausts the inside of the differential exhaust pipe 41 and depressurizes it by sucking the gas in the differential exhaust pipe 41 from the intake port and discharging it to the outside from the exhaust port. Yes.

  The capillary tube 45 is, for example, a quartz thin tube having an inner diameter of about 0.3 mm, an outer diameter of about 0.4 mm, and a length of about 10 cm. The capillary tube 45 has one end connected to the differential exhaust pipe 41 and the other end directly connected to an ionization chamber (not shown) in the detection device 39. The capillary tube 45 is configured to connect the inside of the downstream pipe of the differential exhaust pipe 41 and the inside of the ionization chamber of the detection device 39 so that they can flow while maintaining a pressure difference.

  The detection device 39 is a mass spectrometer that performs sample analysis by mass spectrometry, for example. The detection device 39 includes an ionization chamber (not shown) to which the capillary tube 45 is connected, a detection unit (not shown) for detecting ions of a substance sent from the ionization chamber, and the inside of the detection device 39 in a reduced pressure state. And a vacuum pump 47 for maintenance. Note that mass spectrometry has high resolution and low false alarm rate.

The ionization chamber ionizes a substance contained in the airflow sent through the capillary tube 45 to generate ions.
The detection unit separates and detects ions generated by the ionization chamber based on the difference in mass, and analyzes the structure and composition of the substance. The detection unit is configured to send the obtained spectrum of mass spectrometry to the determination device.

The vacuum pump 47 is configured to maintain a high vacuum state of about 10 ⁻³ Pa in the detection device 39, particularly in the ionization chamber. Thereby, the ion produced | generated in the ionization chamber is sent to a detection part stably and without decomposing | disassembling. The pressure in the detection device 39 can be measured by a pressure gauge (not shown) provided between the capillary tube 45 and the differential exhaust pump 43. A heater (not shown) is provided around the outer periphery of the detection device 39 so that the wall surface of the detection device 39 and the ionization chamber are heated.

  The determination apparatus has a database of mass analysis patterns (for example, relationship between intensity and mass number) of dangerous substances such as various explosives measured in advance. As shown in FIG. 5, this determination apparatus collates the mass analysis spectrum of the substance sent from the detection unit with the mass analysis pattern of the explosive on the database to determine whether the substance is a dangerous substance such as an explosive. It comes to judge. The determination result obtained by the determination device is output as analysis information, and is sent to the server 7 in association with the identification information acquired by the identification information acquisition machine.

The second gate 5 includes an identification information reacquisition machine (identification information reacquisition unit) 49 that reacquires identification information of the person 9 that has passed through the first gate 3.
The identification information reacquisition machine 49 reads the ticket number possessed by the person 9 and reacquires the identification information of the person 9 (hereinafter, the information acquired by the identification information reacquisition machine 49 is “reacquired”. "Identification information"). The reacquisition identification information acquired by the identification information reacquisition machine 49 is sent to the server 7.

  The server 7 stores identification information and analysis information sent in association with the identification information acquisition device and the determination device. Further, the server 7 collates the reacquisition identification information sent from the identification information reacquisition machine 49 with the stored identification information. The opening / closing of the second gate 5 is controlled based on the analysis information associated with the identification information that matches the reacquired identification information.

  Specifically, the server 7 determines that the analysis information of the substance associated with the identification information that matches the re-acquisition identification information of the person 9 acquired by the identification information re-acquisition machine 49 is explosives or the like in the first gate 3. If it is determined that the substance is not a dangerous substance, the second gate 5 is opened to allow the person 9 to pass therethrough. On the other hand, the first gate 3 is determined to be a dangerous substance such as explosives. In the case where it is a trap, the second gate 5 is blocked to prevent the person 9 from passing therethrough.

The operation of the sample collection apparatus 1 according to the present embodiment configured as described above, the substance analysis system 10 including the sample collection apparatus 1 and the inspection system 100 including the substance analysis system 10 will be described with reference to the flowchart shown in FIG. I will explain.
When the person 9 enters the first gate 3 (step SA1), the ticket number given to the ticket is read by the identification information acquisition machine, and the identification information of the person 9 is acquired. Subsequently, in the air shower 21 of the material analysis system 10, air (airflow) is blown to the person 9 for a predetermined time, and the sample adhering to the human body or clothes is blown off (step SB1).

  The sample blown off from the person 9 rides on the airflow and flows to the floor 15 and is sucked into the suction port 23 together with air. When the air passes through the trap filter 25 below the floor 15, the sample mixed in the air adheres to the adsorbent 31. Thereby, the sample adhering to the person 9 is captured by the trap filter 25 (step SB2).

  When the ejection of air from the air shower 21 is completed, the trap filter 25 attached to the flow path 32 is conveyed to the vaporization container 11 by the exchange device (step SB3), and a new trap filter 25 stocked in the filter buffer is It is attached to the flow path 32 (step SC1).

  In the first gate 3, by using the walk-through type sampling device 1, a sample can be efficiently collected in a short time. Specifically, the identification information can be acquired and the sample can be collected in about 3 seconds from when the person 9 enters the first gate 3 until it passes. Further, since the trap filter 25 is exchanged for each person 9, the sample can be captured individually.

  Subsequently, the person 9 who has passed through the first gate 3 goes to the second gate 5, during which the sample captured by the trap filter 25 is analyzed by the sample analyzer 13.

In the vaporization container 11, the sample adsorbed on the adsorbent 31 of the trap filter 25 is heated and vaporized under atmospheric pressure conditions by the operation of the vaporization heater 35. Further, in the detection device 39, the inside of the ionization chamber is maintained in a high vacuum state of about 10 ⁻³ Pa by the operation of the vacuum pump 47. The pressure in the detection device 39 can be measured by a pressure gauge provided between the capillary tube 45 and the differential exhaust pump 43.

  In this situation, in the differential exhaust pipe 41, the differential exhaust pipe 41 is evacuated by the operation of the differential exhaust pump 43 to be in a decompressed state, and the substance vaporized in the vaporization container 11 together with the air flow is differential exhaust pipe. 41 is aspirated. The air flow including the substance sucked into the differential exhaust pipe 41 is heated to 100 ° C. or more and 200 ° C. or less by the pipe heater 42, and the entire inside of the differential exhaust pipe 41 is heated, so that the substance flows on the inner wall. It passes through the differential exhaust pipe 41 without adhering and staying. A part of this airflow is introduced into the detection device 39 from the downstream side of the differential exhaust pipe 41 through the capillary tube 45.

  Here, the valve mechanism of the regulating valve 44 is adjusted to control the exhaust flow rate of the differential exhaust pump 43, and for example, the air flow containing the substance is sucked into the differential exhaust pipe 41 at a flow rate of about 100 sccm. Then, the pressure in the pipe on the downstream side of the differential exhaust pipe 41 is maintained in a reduced pressure state of 50 Pa or more and 70 kPa or less. In addition, by operating the differential exhaust pump 43, the air flow is discharged from the exhaust port at a flow rate of about 98 sccm, and a part of the air flow is introduced into the detection device 39 through the capillary tube 45 at a flow rate of about 2 sccm. .

By doing so, the pressure difference between the inside of the downstream pipe of the differential exhaust pipe 41 and the inside of the ionization chamber of the detection device 39 maintained at about 10 ⁻³ Pa is the inside of the vaporization container 11 under atmospheric pressure conditions. Therefore, the pressure difference between the pipe on the downstream side of the differential exhaust pipe 41 and the inside of the ionization chamber should be maintained using a flow path with little pressure loss. Can do.

  That is, the pressure difference between the differential exhaust pipe 41 and the detection device 39 can be maintained using the capillary tube 45 having an inner diameter of 0.3 mm and a tube length of 10 cm. As a result, the time taken to pass through the capillary tube 45 can be greatly reduced, and the substance vaporized in the vaporization vessel 11 can be introduced into the detection device 39 in a short time. In addition, the trap filter 25 heated in the vaporization container 11 is conveyed to a filter buffer (step SC2).

  In the detection device 39, sample analysis is performed by mass spectrometry. Specifically, the substance introduced into the ionization chamber is ionized and the ions are sent to the detection unit. Then, the ions are separated and detected by the difference in mass by the detection unit, and the structure and composition of the substance are analyzed. The spectrum of mass spectrometry analyzed by the detection unit is sent to the determination device (step SB4).

  In the determination device, the mass spectrometry spectrum of the substance sent from the detection unit is collated with the mass analysis pattern of the dangerous substance such as explosive on the database (step SB5), and it is determined whether the substance is a dangerous substance such as explosive. (Step SB6). The determination result is output as analysis information from the determination device, and is sent to the server 7 in association with the identification information acquired by the identification information acquisition machine.

  By adopting the material analysis system 10 including the sample introduction device 37 that can introduce the material into the detection device 39 in a short time, the material vaporized in the vaporization vessel 11 is sucked into the differential exhaust pipe 41. Therefore, a detection signal of ions can be obtained in the detection device 39 after about 1 second. Therefore, while the person 9 moves from the first gate 3 to the second gate 5, the identification information of the person 9 and the analysis information of the substance can be stored in the server 7.

  In the second gate 5, the ticket number of the person 9 is read again by the identification information reacquisition machine 49 and sent to the server 7 as reacquired identification information. In the server 7, the reacquisition identification information sent from the identification information reacquisition machine 49 is collated with the stored identification information. The opening / closing of the second gate 5 is controlled based on the analysis information of the substance associated with the identification information that matches the reacquired identification information.

  For example, when the analysis information of the substance is determined not to be a dangerous substance such as explosive (step SB6 “OK”), the second gate 5 is opened (step SA2), and the gate of the person 9 is displayed. Passage is possible. On the other hand, if the analysis information is determined to be a dangerous substance such as gunpowder, the second gate 5 is blocked (step SA3) and the person 9 is prevented from passing through the gate. In this case, the person 9 receives a job question or the like.

  As described above, according to the sampling apparatus 1 according to the present embodiment, the substance analysis system 10 including the sampling apparatus 1, and the inspection system 100 including the substance analysis system 10, sample collection and substance analysis are performed. The 1st gate 3 and the 2nd gate 5 in which the possibility of passage of an inspection area is performed can be installed apart. By detecting the substance before the person 9 reaches the second gate 5, it is possible to avoid congestion of the examination of the person 9 in the substance analysis system 10. Therefore, even when there are a large number of passengers, etc., it is possible to efficiently inspect dangerous substances in a short time and prevent the suspicious person from entering the transportation means of transportation beyond the second gate 5 or suspicious objects from being brought in. it can.

  In the present embodiment, the air shower 21 has been described by exemplifying a rectangular tube shape including the floor 15, the ceiling 17, and the pair of walls 19, but instead, for example, from the floor and the pair of walls. You may adopt something like a train ticket gate. In this case, air may be blown from the lateral direction to the person 9 by the air jets disposed on the pair of walls. Further, in the present embodiment, the person 9 is exemplified and described as the object to be collected. However, for example, a substance attached to an article such as baggage may be inspected.

  In the present embodiment, the mass spectrometer is used as the detection device 39 to detect dangerous substances by mass spectrometry. Instead, ion mobility spectrum analysis (IMS) is used instead. The hazardous substance may be detected by luminol chemical fluorescence reaction analysis, Raman spectroscopic analysis, gas chromatography mass spectrometry (GC-MS), or the like.

In addition, the sampling apparatus 1 according to the present embodiment, the substance analysis system 10 including the sampling apparatus 1, and the inspection system 100 including the substance analysis system 10 can be modified as follows.
For example, as illustrated in FIG. 7, the sampling device 201 may further include a fluoroscopic device using millimeter wave electromagnetic waves. In this case, the millimeter wave transmitting antenna and the receiving antenna 221 may be disposed on the wall 19 of the air shower 21. In this way, it is possible to determine whether or not the person 9 owns the dangerous substance in addition to whether or not the person 9 handles the dangerous substance such as explosives.
