Handheld Fluorescent Raman

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).

This product is the world's first integrated fluorescence quenching and Raman, explosive trace screening and confirmation of the hand-held integrated machine, light weight and easy to carry.
