Handheld Fluorescent Raman Technology for Explosive Detection - China Suppliers and Factory Solutions
Product Introduction
▲ Fluorescent Quenching
Trace explosive detector is based on fluorescence technology. When the polymer fluorescent material inside the instrument contacts the explosive molecule, its fluorescence intensity and peak position will change. This change is recorded by the high sensitivity detector inside the machine, and whether the explosives can be found on the measured object through analysis.
Fluorescent technology is used to achieve a large range of trace screening of suspicious people and objects. Suspicious people, items, parcels and unmanned objects can be checked by external wiping or inhalation, without opening the bag, to achieve danger warning.
▲ Raman Spectral Detection
The principle of Raman spectral detection is that when light hits the molecule, the frequency of the light scattered by the molecule changes, and this frequency change corresponds to the molecular structure one by one. By measuring the change of the scattering light frequency, the structure of the molecule can be identified, and the composition of the material determined.
Due to the unique advantages of Raman's principle — no contact, high accuracy, and fast speed — it is particularly suitable for the measurement of solid and liquid suspicious explosives, flammable and explosive, toxic and harmful substances. Combined with solid-liquid sampling cap, it can realize the measurement of trace substances (liquid 5 µl, solid 5 mg). Raman products with transmitted light path, spatial direct coupling and confocal technology offer small size, light weight, fast speed (less than 5 seconds), high accuracy, non-contact operation without environmental interference, and can detect concentrations as low as 5% (5 µl). The algorithm enables fast and accurate analysis of mixture components, realizing rapid identification of three mixed components in less than 5 seconds.

Frequently Asked Questions (FAQ)
Q
What is the detection principle of this handheld explosive detector?
This device combines two detection technologies: Fluorescent Quenching and Raman Spectroscopy. Fluorescent quenching detects trace explosives by measuring changes in fluorescence intensity when polymer fluorescent material contacts explosive molecules. Raman spectroscopy identifies substances by analyzing the frequency shift of scattered light, which corresponds uniquely to molecular structures.
Q
What is the minimum detectable concentration for fluorescent quenching?
The fluorescent quenching module offers extremely high sensitivity, capable of detecting explosive trace amounts as low as 0.1 ng, making it highly effective for security screening applications.
Q
How many substances can the Raman database identify?
The built-in Raman database contains more than 10,000 substance types, including 200+ drugs and precursor drugs, 200+ new psychoactive substances, 106 fentanyl variants, and over 100 synthetic cannabinoids — covering explosives, flammable materials, and toxic/harmful substances.
Q
How fast is the detection speed, and does it require opening bags or direct contact?
Detection is completed in ≤ 3 seconds. The device supports non-contact detection — suspicious persons, items, parcels, and unattended objects can be screened by external wiping or air inhalation, without the need to open any bag or packaging.
Q
Can this device detect mixed substance components?
Yes. The advanced Raman algorithm supports rapid identification of up to three mixed components simultaneously, completing analysis in less than 5 seconds. It can also detect liquid concentrations as low as 5% (5 µl) and solid trace amounts as small as 5 mg.
Q
What makes this product unique compared to conventional explosive detectors?
This is the world's first handheld device that integrates both fluorescence quenching and Raman spectroscopy into a single unit. It combines trace explosive screening (fluorescence) with precise substance identification (Raman) in a compact, lightweight, portable form — offering an accuracy rate of ≥ 99% and a laser power range of 1–500 mW continuously adjustable.
