Description

Technical Field

[0001] The present application relates to the field of detection and analysis technology, and in particular, to a gate system and a sample inspection method for sample detection. Background Art

[0002] In order to combat terrorist activities and drug smuggling, ion mobility spectrometry, gas chromatography, gas chromatography-ion mobility spectrometry, gas chromatography-mass spectrometry and other technologies are currently mainly used to detect trace drugs and explosives. In many occasions such as airports, railways, highways, and conference entrances and exits, there is an urgent need to provide a device that can quickly and effectively collect and analyze high-boiling point samples such as trace drugs and explosives that are difficult to volatilize from tickets, IC cards or identity cards.

[0003] The existing detection of trace drugs and explosives is mainly done by wiping the clothes of the subject with a test paper, sampling the surface of the luggage bag, and then analyzing it with an instrument through thermal analysis. However, there are few reports on the technology suitable for sampling and analyzing drugs, explosives, etc. on tickets, IC cards or ID cards. Among them, Smiths published a method of using an air pump to suck air and adsorb the sample with an adsorption belt; Hitachi reported a method of using a fan-shaped beam airflow to sweep the surface of the certificate and combining it with a tornado suction technology for sampling. It can achieve sampling and testing of tickets, IC cards, ID cards, etc., but its sampling efficiency is low, the detection sensitivity of the instrument is high, and it is difficult to implement.

[0004] In an existing sample capture and sample analysis device, the sample capture part is equipped with a sampling belt wound on two spools, and the sampling belt is coated with an adsorbent material. When sampling, the pump is started to suck air to suck the sample into the sampling belt and adsorb it. After sampling, the part adsorbed with the sample is sent to the thermal desorption zone for instant desorption and then sent to GC-IMS for detection and analysis. This technology can solve the problem of automatic and continuous sampling, and is suitable for sampling and detection of cards and certificates. However, its essence is still aspiration sampling, and this sampling method has low efficiency in collecting samples of drugs and explosives with high boiling points and strong adhesion.

[0005] In an existing gate security inspection device, a fan-shaped beam airflow is used to sweep the surface of the card and certificate, and a tornado suction sampling device is used to collect samples that fall from the card and certificate, and then the samples are sent to the detection device for detection. This method of using a strong fan-shaped beam airflow to sweep the surface of the card and certificate and combining it with tornado sampling has significantly improved the sampling effect compared to direct suction sampling. However, while the fan-shaped beam airflow is used to blow the samples off the card and certificate and they are captured by the tornado sampler, a considerable portion of the blown samples will be lost because they are not captured by the tornado sampling device, and high-boiling point particles such as drugs and explosives are not easily knocked down by the airflow after being adsorbed by the card and certificate. Therefore, this sampling technology is difficult to further improve the sampling effect of drugs and explosives.

[0006] Therefore, a new gate system and sample inspection method for sample detection are needed.

[0007] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present application and therefore it may contain information that does not constitute the prior art that is already known to a person of ordinary skill in the art.

[0039] Figure 1FIG. 1 is a schematic diagram of a gate system for sample detection according to an exemplary embodiment. Figure 1 As shown, the gate system 10 for sample detection includes a containing device 102, a wiping sampling device 104, an air sampling device 106, and a detection device 108. 1 is a ticket to be detected, and 13 is a housing of the gate system 10 for sample detection.

[0040] The accommodating device 102 is used to accommodate the inserted ticket to be tested, and the accommodating device 102 can also be used to read and verify the information of the ticket to be tested placed in the accommodating device. In this application, the ticket to be tested can include, for example, tickets, IC cards, identity cards and other documents.

[0041] The wiping sampling device 104 includes: a wiping sampling belt 1042, and the wiping sampling belt 1042 is used to drive the ticket to be tested to move in the containing device and wipe and sample the ticket to be tested.

[0042] The suction sampling device 106 is used to collect the sample dropped from the wipe sampling device.

[0043] The detection device 108 is used to detect the sample and output the detection result.

[0044] Figure 2 FIG. 1 is a schematic diagram of a receiving device in a gate system for sample detection according to an exemplary embodiment. Figure 2 As shown, the accommodating device 102 includes: a card slot 1022 , an information reader 1024 , a spring top bead 1026 , and a spring piece 1028 .

[0045] The card slot 1022 is used to carry the ticket to be tested.

[0046] The information reader 1024 is used to read the information of the ticket to be tested through a built-in chip and verify the information. The information reader may include an information reading chip, through which the content of the ticket, IC card, identity card and other documents is read and verified.

[0047] The spring top ball 1026 is used to increase the contact pressure between the ticket to be tested and the wiping sampling belt, so that the ticket to be tested contacts the wiping sampling belt.

[0048] The spring piece 1028 is used to eject the ticket to be tested from the card slot after the information verification of the ticket to be tested is completed.

[0049] Figure 3 FIG. 1 is a schematic diagram of a wiping sampling device in a gate system for sample detection according to an exemplary embodiment. Figure 3As shown, the wiping sampling device 104 includes: a wiping sampling belt 1042 , a motorized roller 1044 , and a semiconductor cooling sheet 1046 .

[0050] Among them, the electric roller 1044 is used to drive the wiping sampling belt to transmit.

[0051] The semiconductor cooling sheet 1046 is used to cool the wipe sampling belt.

[0052] Figure 4 FIG. 1 is a schematic diagram of a sampling device in a gate system for sample detection according to an exemplary embodiment. Figure 4 As shown, the air inhalation sampling device 106 includes: a sampling air inlet 1062 , a central rotating airflow outlet 1064 and a peripheral rotating airflow outlet 1066 , a sampling head 1068 , an O-ring 1067 , and a trumpet-shaped sampling head cover 1069 .

[0053] The sampling suction port 1062 is placed below the wiping sampling device 104 and is used to suck the sample into the sampling device;

[0054] The airflow outlet is used to form an airflow, and the airflow outlet includes: a central rotating airflow outlet 1064 and a peripheral rotating airflow outlet 1066 .

[0055] The sampling head 1068 is used to collect the sample, and the air sampling device 1068 includes: a tornado sampling device. The air sampling device 1068 may also include, for example, a thermal desorption chamber / cavity, a conventional air sampling pump air sampling method, and other sampling devices, but the present application is not limited thereto.

[0056] The air inhalation sampling device 106 further includes: an O-ring 1067 and a trumpet-shaped sampling head cover 1069 .

[0057] In an exemplary embodiment of the present disclosure, the detection device 108 includes: a sample exchange semipermeable membrane, a chromatographic column, and an ion transfer tube. The sampling detection device can be, for example, any type and variety of detection equipment in the prior art to achieve sampling of the sample, and the present application is not limited thereto.

[0058] Among them, a semipermeable membrane is a membrane that only allows certain molecules or ions to diffuse in and out, and is selective for the passage of different particles. Examples include cell membranes, bladder membranes, parchment, and artificial collodion membranes. Modern semipermeable membranes are also used to form porous walls and allow appropriate compounds to precipitate in their pores. In the present application, any one or a combination of the above semipermeable membranes for sample exchange is used, and the present application is not limited thereto.

[0059] Among them, chromatographic columns can be divided into two categories: packed columns and open tube columns. Most of them are made of metal or glass. There are straight tubes, coils, U-shaped tubes and other shapes. Liquid chromatography usually uses packed columns. Chromatographic columns can be divided into analytical and preparative types according to their uses, and the size specifications are also different: ① Conventional analytical column (constant column), inner diameter 2-5mm, column length 10-30cm; ② Narrow bore column (narrow bore,), inner diameter 1-2mm, column length 10-20cm; ③ Capillary column (microcolumn), inner diameter 0.2-0.5mm; ④ Semi-preparative column, inner diameter>5mm; ⑤ Laboratory preparative column, inner diameter 20-40mm, column length 10-30cm; ⑥ The inner diameter of the production preparative column can reach tens of centimeters. The inner diameter of the column is generally determined according to the column length, filler particle size and reduced flow rate, in order to avoid the tube wall effect. In this application, the chromatographic column can be any one or a combination of the above, and this application is not limited to this.

[0060] Among them, the ion transfer tube is a key component for calculating the ion mobility spectrum. In the ion transfer tube, ions fly under the traction of the electric field force and collide with the migration gas, so that ions of different sizes are separated and arrive at the detector one after another. In this application, the ion transfer tube can be a combination of any model and variety in the prior art, and this application is not limited to this.

[0061] As mentioned above, drugs, explosives, etc. have high boiling points and are not easy to volatilize. When sampling drugs, explosives, etc. by suction, the tickets to be tested with drugs or explosives attached to them need to be heated to a certain temperature (higher than 80°C) to cause the drugs or explosives to volatilize before a more satisfactory sampling result can be obtained. However, IC cards and ID cards contain built-in chips and the main body is made of plastic. High temperature will not only cause the card to deform but also damage the chip. Wiping sampling for drugs and explosives has a better effect. In this application, after wiping the tickets to be tested with the wiping sampling belt 1042 and adsorbing the sample, the wiping sampling belt 1042 is hit by the high-temperature rotating airflow in the suction sampling device 106 to vaporize the sample. Then, the sample passes through the tornado suction sampling port in the suction sampling device 106 and then passes through the sample exchange semipermeable membrane in the detection device 108, and is detected by the chromatographic column and ion migration analysis.

[0062] Figure 5 FIG. 1 is a schematic diagram of a gate system for sample detection according to another exemplary embodiment. Figure 5 As shown, the working process of the gate system 10 for sample detection can be described as follows:

[0063] The person who is to pass through the gate inserts the ticket / IC card / ID card 1 into the slot of the ticket card slot 1022 to be tested. A spring top ball 1026 is provided on one side of the slot. The spring top ball 1026 can force the ticket / IC card / ID card 1 to have good contact with the wiping sampling belt 1042. The wiping sampling belt 1042 is driven by the electric roller 1044. At the same time, the wiping sampling belt 1042 will also drive the ticket / IC card / ID card 1 to move synchronously. The ticket information reader 1024 to be tested reads and verifies the ticket information to be tested. After the ticket / IC card / ID card 1 contacts the spring piece 1028 at the end of the ticket card slot 1022 to be tested, the spring piece 1028 ejects the ticket / IC card / ID card 1 from the slot, and the passenger or relevant personnel can take out the ticket / IC card / ID card 1. At the same time, the wiping sampling process of the passenger or relevant personnel's ticket / IC card / ID card 1 is completed.

[0064] The wipe sampling belt 1042 adsorbed with the certificate sample continues to drive under the drive of the motor and passes over the tornado sampler. Among them, the outer surface of the tornado sampling head 1068 is provided with a heating film, and the heating film is coated with thermal insulation cotton. The purified air or nitrogen is heated through the inner cavity and the outer cavity from the four air inlets at the lower end of the tornado sampler, and then rotated and discharged from the central rotating airflow outlet 1064 and the peripheral rotating airflow outlet 1066. Among them, the high-speed rotating airflow discharged from the peripheral rotating airflow outlet 1066 is a large-flow high-speed rotating airflow, which is mainly used to form a local negative pressure of the tornado; the low-speed high-temperature airflow discharged from the central rotating airflow outlet 1064 is mainly used to heat the wipe sampling belt 1042 and force the sample to desorb. Among them, in order to enhance the negative pressure effect of the tornado, a trumpet-shaped sampling head cover 1069 is provided on the upper part of the tornado sampler. The trumpet-shaped sampling head cover 1069 can focus the cyclone and enhance the negative pressure effect of the tornado. The trumpet-shaped sampling head cover 1069 is fixed to the tornado sampler by an O-ring 1067. The precipitated sample is analyzed and detected by the semipermeable membrane, chromatographic column and ion migration tube of the detection device 108 under the negative pressure of the tornado sampler and the sampling suction pump at the lower end of the sampling suction port 1062.

[0065] The gate system for sample detection according to the present application has a wide range of applications and can perform rapid sampling and detection of non-volatile substances. It is suitable for on-site rapid inspection of personnel passing through airports / highway / railway checkpoints, large conference entrances, etc., making up for the problems of difficult sampling and poor detection accuracy of non-volatile substances such as drugs and explosives in traditional sampling methods, and creating a new model for customs inspection of trace substances.

[0066] Those skilled in the art will appreciate that the above modules can be distributed in the device according to the description of the embodiment, or can be changed accordingly and only used in one or more devices different from the embodiment. The modules of the above embodiments can be combined into one module, or further divided into multiple sub-modules.

[0067] Figure 6 The figure is a flow chart of a sample inspection method according to an exemplary embodiment.

[0068] like Figure 6 As shown, in S602, the information of the ticket to be tested placed in the containing device is read and verified. The information of the ticket to be tested placed in the containing device is read and verified by the gate system; the gate system includes: a containing device, which is used to read and verify the information of the ticket to be tested placed in the containing device; a wiping sampling device, including: a wiping sampling belt, which is used to drive the ticket to be tested to move in the containing device and wipe and sample the ticket to be tested; a sampling device, which is used to collect samples dropped from the wiping sampling device; and a detection device, which is used to detect the sample and output the detection result.

[0069] In S604, the ticket to be tested is wiped and sampled by a wipe sampling belt in a wipe sampling device.

[0070] In S606, the sample is blown off the wiping sampling belt by air flow, and the sample dropped from the wiping sampling belt is collected.

[0071] In S608, the sample is tested and the test result is output.

[0072] According to the sample detection method of the present application, a wiping sampling method with good sampling effect on samples, especially high-boiling point samples that are difficult to volatilize, and a tornado sampling mode with high sampling and collection efficiency for gas samples are used in combination. The combination of these two sampling modes, on the one hand, avoids the risk of directly heating IC cards, identity cards, etc. and causing damage to the documents, on the other hand, compared with traditional thermal analysis and suction sampling methods, the use of a tornado sampler not only simplifies the design, but also has a better effect on the collection of precipitated samples than traditional suction methods.
