022. INSTRUCTION The Explosive/Narcotics Trace Detector - Tabletop is an explosives and narcotics detection device. Based on the principle of ion mobility spectrometry, it can accurately detect particles or vapor of explosives and narcotics, and report the ingredient names. With the superior technical features of fast response, high precision, low power consumption and easy to operate and maintain, the Detecto is widely used for security check in airports, seaports, customs checkpoints, border crossings, metro stations, railway stations and other importation occasions.2.1 Working Principle The Explosive/Narcotics Trace Detector - Tabletop uses a reliable trace detection technology based on the ion mobility spectrometry. The core component of the Detector is the drift tube, which is schematically illustrated in Figure 2.1. It mainly included the ion source, the ion gate, the drift region and the detector.The working principle of the drift tube is: at atmospheric pressure, any vapors or microscopic particles of target materials collected on the sample trap are released into the detection system by placing the sampled trap into the inlet on the desorber Desorbed vapors are carried into the ion source on a stream of clean, dry air. Ions of the sample formed in the ion source passed through the pulse opened ion gate and entered the drift region with an even electric field. The velocity of the ion is proportional to the electric field intenisty the electric field intensity is less than 1000V/cm:In which v is the velocity of the ion, E is the electic field intensity, and K is the ion mobility. K is constant when E is less than 1000V/cm, and decided by ion structure, mass, charger number and the type of the drift gas. The ion mobility of each target ion differs sufficiently so that each can be uniquely identified. Meanwhile, the quantity can be determined by the direct proportion between the peak area and the logarithmic values of the concentration.Figure 2.1 Schematic diagram of the drift tube.V = KE,Carrier gasIon Source Ion Gate Drift region Drift gasDetectorGas outletDesorberDrift time

5. DETECTION This chapter introduces the basic operation of the Detector, including start-up, shut down, check, calibration, detection, etc.5.1 Start-up and Warm-upStart-up Turn on the power switch on the rear of the Detector, and turn on the On-off switch on the front of the Detector, the system will enter the self-check (about l5s).Login After the self-check is completed, the system enters the Login page, as shown in Figure 4.1. Enter the Username and Password (the default Username is “user” and the Password is “l2345”), select the detection mode (Explosives-Only, Narcotics- Only or Dual-Mode), and click <Login>, the system starts to warm up.Warm-up The system need approximately 30 minutes to stabilize. The screen displays the temperature message during this period, as shown in Figure 4.2.5.2 Calibration The ionization process in the detector is affected by the ambient temperature, the moisture, and the pressure; On the other hand, the ion mobility, which is used to identify the substance, may vary slightly due to the pressure, the temperature, and the amount of humidity in the system. So, calibration is required in order to ensure the accuracy of the test results.Calibration is recommended in the following circumstances: 1. After the maintenance of the Detector (such as replacing the filter media, repairing any parts, etc.); 2. After changing the parameters (such as temperature, flow, etc.);; 3. Significant changes occur to the absolute pressure, temperature, humidity, etc. Note: Time for Warm-up depends on the frequency of utilization. If the detector is used every day, the warm-up takes about 30min for the first cold start of a day; If the detector has not been used more than one week, the warm-up takes about 4 hours above for the first cold start; If the detector has not been used for more than a month, the warm-up needs 24hs above for the first cold start.24
Calibration types The system can be calibrated automatically or manually. The system will calibrate automatically before every detection. Manual calibration is only needed when the system give false results or when the check fail.Manual Calibration Tools The calibration must be performed with a specified tool come with the Detector, as shown in Figure 3.4.Manual Calibration Process 1. Enter the System Setup interface as shown in Figure 4.18 and initialized the system. 2. Wipe the calibration stick on the optimum sampling area about 1 to 1.5 cm from the round end of a sampling trap, which can be seen in Figure 5.1. 3. Enter the Detection page as shown in Figure 5.2, and click <Calibrate> button, the system will start the calibration process, and prompt “Please insert the sample trap…”; Insert the calibration trap prepared in step l into the sample inlet. The Detector will automatically perform the calibration process and give the results \"Calibrate succeeded\" or \"Calibrate failed\" in the prompts bar. If the calibration fails, try wipe the sample cloth a few more times with the calibration stick and calibrate again.WARNING: It suggested to do the manual calibration cautiously as it will change the core parameter.Figure 5.1 Collect the Calibration Sample.Figure 5.2 Calibration. WARNING: Do not take too much sample when sampling for calibration. Otherwise the instrument will be contaminated and the cleaning time is much longer.25
5.3 Check Check is a fundamental and important operation, which is to determine whether the system is in a normal operation and can give an accurate result.Check is recommended in the following circumstances: 1. After the start of the system, before any detection; 2. Above 8 hours from the last check; 3. After calibration; 4. After the maintenance of the Detector (such as replacing the filter media, repairing any parts, etc.); 5. After changing the parameters (such as temperature, flow, etc.); 6. Significant changes occur to the absolute pressure, temperature, humidity, etc.3. After calibration; For the last three circumstances, it is suggested that check first, and calibrate if check fail.Check Tools The check must be performed with a specified tool come with the Detector, as shown in Figure 3.5, whose appearance is green.Check Process The check must be performed with a specified tool come with the Detector, as shown in Figure 3.5, whose appearance is green. 1. Wipe the check stick on the optimum sampling area about 1 to 1.5 cm from the round end of a sampling trap, which can refer to Figure 5.1. 2. Enter the Detection page and press <Check> button, or click <OK> in the pop-up inquiry page as shown in Figure 5.3, the system will start the check process,and prompt “Please insert the sample trap…”; Insert the check trap prepared in step l into the sample inlet. The Detector will automatically perform the check process and give the results \"Check succeeded\" or \"Check failed\" in the prompts bar. If the check fails, try to wipe the sample trap a few more times with the check stick and check again.Figure 5.3 Check.26
5.4 Detection It is emphasized again that the Detector can detect only after it is ready.Sampling method Three sampling methods can be used with the Detector: Surface Wipe Sampling by hand; Surface Wipe Sampling with the hand-wand; Inspect vapor samples with the Detector. For details on how to wipe sampling with the hand-wand, see section 3.3. The following highlights the precautions on Surface Wipe Sampling. 1. For trace particles, use the sample trap to wipe the surface of the object inspected for three times. 2. For large particles of solid samples or high concentration liquid samples, use the sample trap to wipe the object, then flick the sample trap to remove most of the sample, and wait for the sample trap to dry if necessary before insert it into the inletSteps for Detection 1. Enter the Detection page (see Figure 4.4); 2. Click <Detect> when the system is ready for detection, and it will prompt ‘please enter the sample trap’ 3. Insert a blank sampler trap into the sample inlet, and the system will start the detection and prompt the result several seconds later. Conduct more than 2 tests continuously without alarm, indicating that the sampler trap is clean and usable. 4. Take out the blank sampler trap and collect samples according to the sampling method mentioned above. 5. Insert the sampler trap into the inlet. The sample will be desorbed instantly with high temperature in the desorber. The sample molecules are carried into the ion drit tube by a stream of clean, dry air. Then the detection process is completed automatically. 6. The result will show on the prompt bar. If no suspicious is found, it will prompt for ‘No Suspicious’, as shown in Figure 5.4 (A); If any suspicious is found, the Detector will alarm with sound or light, and prompt for the name and relative content of the suspicious, as shown in Figure 5.4 (B); WARNING: 1) Gloves are required in the sampling operation. Avoid touching the sampling end; 2) The sampler trap must be clean, which can be confirmed by blank detection. WARNING: The sampling trap cannot be taken out during the detection process. Otherwise the Detector cannot give a correct result.27
7. Remove the sample trap from the inlet; 8. Click <Print> to print the detection results, including the time, the username, the suspicious name and the spectrum. 9. Click <Confirm>, the system will start the automatic clean. If the system has not entered the ready state after the automatic clean, click <Clean> to continue cleaning. 10. Repeat the above steps using a new sample trap to detect the next sample. WARNING: It is not advised to continuously clean the system for a long time. Otherwise the module of the injector may be damaged and the life of the pump will be shortened. Note: The non-alarm sample trap can be reused, but it should be used no more than 5 times in order to ensure the accuracy.Figure 5.4 (A) No suspicious is detected.Figure 5.4 (B) Some suspicious are detected.28
5.5 Library Update The library can be updated in real time according to the application. The library needs to be updated when: 1. Receiving an invitation to update the library by the manufacturer based on its latest research and development results. 2. Significant changes occur to the absolute pressure, temperature, humidity, and the Detector cannot accurately detect samples after calibration. 3. Users need to detect new suspect explosives or narcotics which are not list in the library.In the above three conditions, users can contact the manufacturer to update the substance list. The update of the substance list can be realized in two ways: 1. Software upgrade: Specific steps are shown in Chapter 4.6; 2. Add new substance through the Library page. (Only available for the third circumstance above, and the users have the standard material of the substance to be added.) The detail steps are as follows: 1) Input the basic information Click <Add> button and input the basic information as shown in Figure 5.5, including the name, type (Explosive or Narcotic), detection mode (Negative or Positive). Click <Confirm> and return to the Library page. 2) Determine the drift time Click <Recognize> and enter the Recognization page, as shown in Figure 5.6. Choose the substance name input before, and collect the standard material. Insert the trap into the inlet and observe the change of the spectrum. When there is a new peak appear, click <Stop> and click <Save>. Choose the drift time for the new substance on the pop-up page (shown in Figure 5.7) and click <Confirm>.

6. MAINTENANCE AND TROUBLESHOOTING This chapter provides the essential procedures on how to maintain the Detector. Routine maintenance is required to keep the system calibrated, clean, and dry, and can be performed by non-technical personnel. Read the following attentions carefully before maintenance: 1. The user is prohibited to open the shell or disassemble the ion drift tube in any condition. Otherwise, the manufacturer has the right to refuse to provide any maintenance service. 2. Any maintenance operation should be carried out in the state of disconnecting the power to avoid the danger of burn or electric shock. 3. If there is no test for a long time, the detector is still necessary to operate at least 3-5 times a month to ensure the Detector works well.6.1 Replace the Filter Media The Detector needs to work in a dry and clean environment. So the carrier gas and drift gas needs to be filtered. It is necessary to check whether the gas is dry and clean after continuous operation for a period of time. The filter media should be replaced when needed. The service life of the filter is decided by the use frequency, the humidity and cleanliness of the air outside, the cleanliness of the samples and so on. Generally speaking, if the instrument runs more than 8hs per day, the duration is as follows: 1. Dry area: about 2 month. 2. Wet area: about l month; 3. The area of poor air quality: about 1 month; 4. The sample humidity or concentration is high: half to one month. The replacement steps are as follows: 1. Turn off the detector and open the cover, you can find the two filter containers as shown in Figure 6.1;Figure 6.1 Container in the Detector.32
2. Pull out the filter container with the special tool; 3. Open the container with the hex wrench and the special tool; 4. Remove the filter element; 5. Pour out the used media, and fill with the fresh media; 6. Install the filter element, and close the upper cover; 7. Insert the container with the inlet/outlet to the inner slot of the Detector. 8. Cover the rear cover and complete the replacement.6.2 Inlet Protection The inlet of the desorber is easy to be polluted as it is open to the outside. Please plug the inlet when no samples tested. Once the inlet is contaminated, it should be cleaned immediately to ensure the detection accuracy. If any sample residue is found in the inlet, or the system is polluted and can not be cleaned by the Deep Cleaning, the inlet need to be clean manually. The detail steps are as follows: 1. Cool the Desorber to room temperature and keep the detector in high temperature; 2. Clean the inlet by a q-tip dipped in methanol or isopropanol; 3. Wait for the volatilization of the methanol or the isopropanol; 4. Heat the desorber; 5. Deep cleaning; 6. CheckFigure 6.2 Filter Container.Note: Be sure not to touch the inlet with your hands or unclean objects to avoid contaminating the inlet.33
6.3 Touchscreen Maintenance The maintenance of the touchscreen mainly includes daily cleaning and screen calibration.Clean the Touchscreen Ensure that the power is off before cleaning the touch screen. Use a soft cloth to wipe it gently. Dip some water or methanol when necessary.Calibrate the Touchscreen Enter the main page, press <Adv. SET> then <System Setup> then < Touch-screen Calibration>. Calibrate following the prompts. After completing the calibration, the system will automatically restart.6.4 Change the Printing Paper Explosives & Narcotics trace detector - tabletop has a built-in thermal printer to print the test results, the historical records and the detection spectrum, etc. When the printing paper is used up, the new printing paper needs to be replaced. The steps are as follows: 1. Open the bar switch at the bottom of the printer slightly. 2. Open the upper cover; 3. Remove the core; 4. Locate a new printing paper. 5. Close the paper cover; 6. Power on the Detector, and the paper will come out automatically.34
6.5 Troubleshooting Chart If the Detector fails to operate properly, refer to the Troubleshooting Chart below before calling the factory for service. The chart is designed to help identify and correct many common system problems. Table 1 Troubleshooting Table.Failure to start up Check if the power wires is plugged tightly.No RIP(Peak of the Reaction Ion)1) Clean the system (including the Deep Cleaning, cleaning the inlet):2) If there is still no RIP after Deep Cleaning, call the factory for service.Check Fail1) Wipe the sample trap a few more times with the check stick and check again;2) Calibrate manually;3) System is contaminated, clean the system (including the Deep Cleaning, cleaning the inlet).Manual Calibration Fail1) Wipe the sample trap a few more times with the calibration stick and check again;2) Verify if the sample trap is insert after the prompt “Please insert the sample trap”3) System is contaminated, clean the system (including the Deep Cleaning, cleaning the inlet).False alarm1) Check again:2) System is contaminated, clean the system (including the Deep Cleaning, cleaning the inlet);3) Calibrate manually.No alarm1) Check again:2) Verify the temperature is 180°C for the desorber and 100°C for the detector;3) Collect more sample4) System is contaminated, clean the system (including the Deep Cleaning, cleaning the inlet).No alarm 1) Ensure paper is installed correctly;2) Reboot system to reconfigure the printer.Touchscreen doesnot work1) Re-calibrate touchscreen in Advanced menu.2) Use the mouse.Problem Possible Cause35
