Handheld Fluorescent Raman Technology by China Suppliers - Fast, Accurate Detection from Factory for Explosive Screening
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 no main objects can be checked by external wiping or inhalation, without opening the bag, to achieve danger warning.
Raman: 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, so by measuring the change of the scattering light frequency can know the structure of the molecule, and then identify the composition of this material.
Due to the unique advantages brought by Raman's principle, it has the advantages of no contact, high accuracy and fast speed, which makes it particularly suitable for the measurement of solid, liquid suspicious explosives, flammable and explosive, toxic and harmful substances. Combined with solid-liquid sampling cap can realize the measurement of trace substances (liquid 5 ul, solid 5mg). Raman products with transmitted light path, spatial direct coupling and confocal technology have the advantages of small size, light weight, fast speed (less than 5 seconds), high accuracy, non-contact, without environmental interference, can detect the concentration of 5% (5ul); the algorithm of mixture components fast and accurate analysis, can realize rapid identification of three mixed components (less than 5 seconds).

Frequently Asked Questions
Q
What is the difference between fluorescence quenching and Raman detection in this device?
Fluorescence quenching detects trace explosive molecules by measuring changes in fluorescence intensity and peak position when molecules contact the polymer sensor, achieving ultra-high sensitivity down to 0.1 ng. Raman spectroscopy identifies substances by analyzing molecular light-scattering frequencies matched against a library of over 10,000 compounds, enabling precise chemical identification.
Q
Does the device require opening bags or packages during screening?
No. The fluorescent quenching module enables non-invasive trace screening through external surface wiping or air inhalation — no bag or package needs to be opened. This allows fast, non-intrusive screening of persons, luggage, parcels, and unattended items at security checkpoints.
Q
How quickly can the Raman module identify a substance?
The Raman detection module delivers results in less than 5 seconds per sample. Its advanced mixture-component algorithm can simultaneously identify up to three components in a mixed substance within 5 seconds, making it highly effective for rapid field analysis and real-time security operations.
Q
What categories of substances are covered in the onboard database?
The onboard database contains over 10,000 compound entries, including 200+ types of drugs and precursor chemicals, 200+ new psychoactive substances, 106 fentanyl analogs, and more than 100 synthetic cannabinoids. It also covers a broad range of explosives, flammable materials, and toxic or hazardous substances.
Q
What is the minimum detectable sample size?
The fluorescent quenching module achieves sensitivity as low as 0.1 ng for trace explosive residue detection. Using the solid-liquid sampling cap, the Raman module can analyze liquid samples from as little as 5 µL and solid samples from just 5 mg.
Q
Is this device portable and suitable for field deployment?
Yes. This lightweight, handheld unit integrates both fluorescence quenching and Raman technologies into a single device — the world's first of its kind. Its compact design makes it well-suited for border security, law enforcement operations, customs inspection, and on-site hazardous material identification.
