What is the working principle of the explosive detector?


With the expansion of security inspection market, security inspection products have begun to diversify. There are many common differences, such as micro seismic life exploration instrument and vehicle bottom detector. And some security devices are in the middle of the two, people may have seen, but they do not remember, after all, the amount of use is not as large as the security machine, the security door. For example, liquid explorer, explosive detector, etc., what is the explosive detector?

Explosive detector can be used to detect explosive objects such as bombs. In fact, in addition to detecting explosives, it can also detect drugs, so it is also called drug explosive detector. Its function is very strong. It can detect whether there are explosives, drugs and prohibited chemicals in the target without opening the outer package of the detection target. If the explosive detector is used in the subway station, airport and other places, just use the test paper to clean the passenger's package and analyze the composition of the explosive detector, then you can check whether the bag is explosive. In this way, it can ensure that packages containing explosives are not taken to the subway, and there will be no such tragedies as the explosion of the subway station. So how does the bomb detector work? How does it work?


The working principle of the explosive detector is to collect the extremely small amount of explosive components into the entrance of the explosive detector through vacuum adsorption or scrubbing. After the system transformation and reaction, the charged molecules of the ionized sample enter the ionization gate, and record the flying time of ions in the electric field through the electric field behind the ionization gate. Due to the different ionization characteristics of different substances and the different substances themselves, there will be differences, resulting in different arrival times of the system. According to these time differences, the system can determine the composition of the substance.
