portable trace explosive and drug detector

1, Sensor Features

The DY-150P portable explosive and drug detector is a new generation of explosive and drug trace detection and analysis instrument developed and produced by MYT Technology Co., LTD.

This detector employs advanced photoionization high-resolution ion mobility spectrometry technology, utilizing a vacuum ultraviolet photoionization source without radioactive components. It poses no radiation hazards to humans and is easy to maintain, store, and repair. The device features user-friendly operation, one-touch detection, rapid analysis speed, high sensitivity, portability, and strong environmental adaptability. It can quickly and accurately detect various military explosives and civilian homemade explosives (including black powder, fireworks, and five other types). The prohibited substance database can be flexibly expanded to include multiple banned hazardous materials based on user requirements. The system includes self-cleaning functionality for rapid MYT fication of internal components.

The detector is suitable for airport, subway, port, hotel, church, business center, large gathering and other important public activity places for explosion-proof security inspection, trace detection of explosives and other prohibited substances; it can also be used for teaching and scientific research purposes.

3, Basic Working Principle

The detector employs next-generation ion mobility spectrometry technology, as illustrated in Figure 1.2.1. When the sample molecules undergo thermal desorption through the injection system, they enter the ionization zone of the ion mobility tube via the injection channel and are ionized by a non-radioactive ionization source. The ionized molecules transform from neutral to charged ions. These charged ions then pass through the ion gate-controlled reaction zone into the ion mobility region, where they travel under a uniform electric field to the ion reception zone, where they are converted into electrical signals. The weak electrical signals are amplified by an amplifier and transmitted to the data processing system, ultimately forming the detection spectrum of the ion mobility spectrometry.

Figure 1.2.1 Ion Migration Spectrum Working Principle

The mass-to-charge ratio (m/z) of ions formed from the tested sample molecules varies, resulting in different collision cross-sectional areas. Consequently, ions exhibit distinct migration rates within the migration zone, leading to varying arrival times in the reception zone. Ion mobility spectrometry leverages these differential migration rates to identify specific sample components.
