Core Technical Parameters

Practical Application Cases

1. The Public Security Detachment of a Municipal Public Security Bureau received a report from the masses that there was an illegal explosive manufacturing den in an abandoned factory building in the suburban area. The on-site environment was complex, and a large number of unknown powder, liquid raw materials and semi-finished devices were piled up in the factory building.

2. At the anti-drug inspection site of a border port, when the customs anti-smuggling police inspected an incoming logistics truck, they found that a batch of sealed food gift boxes in the carriage had abnormal weight. After opening the box, no obvious contraband was found, but there was suspicious white powder in the interlayer of the gift box, and the composition could not be judged on site. The police used this equipment to carry out penetration detection on the suspicious powder in the sealed package, and identified the powder as methamphetamine within 5 seconds, with a total weight of 12 kg. The test report and spectrum data issued by the equipment on site provided immediate evidence support for the case investigation. The anti-smuggling police simultaneously controlled the 涉案 personnel and vehicles, followed the clues and successfully destroyed a cross-border drug trafficking gang, realizing on-site rapid inspection and whole-chain crackdown of drug cases.
