Handheld fluorescent Raman composite drug/explosive detector BH2-21AModel

      Handheld fluorescence-Raman combined drug/explosive detector based on fluorescence quenching technology,When the instrument’s internal polymer fluorescent material contacts drug or explosive molecules,Its fluorescence intensity,Peak positions shift,This change is recorded by the machine’s highly sensitive internal detector,Analysis determines whether drugs or explosives are present on the tested object. During detection,For suspicious persons,Items,Packages and unclaimed items can be inspected by simply swabbing or sampling air from their exterior,No need to open packages,Enables large-scale screening and early warning.

       Handheld fluorescence-Raman combined drug/explosive detector extends Raman applications,When light hits molecules of the sample,Light scattered by molecules undergoes frequency shifts,This frequency shift corresponds uniquely to molecular structure,Thus, measuring the frequency shift of scattered light reveals molecular structure,Thereby identifying the substance composition,Non-contact,High accuracy,Fast speed and other features,Especially suitable for solid detection,Liquid suspicious drugs,Precursor chemicals,Explosives,Flammable and explosive,Toxic and hazardous substances, etc..

       Handheld Fluorescence-Raman Combined Explosive & Drug Detector(BH2-21A)Integrates fluorescence quenching and Raman technologies,Enables drug,Toxic and hazardous substances,Detection of explosives, etc.,Uses fluorescence quenching technology to screen suspicious individuals,Trace drug and explosive screening on suspicious items;If alarm is triggered,Then uses Raman for precise qualitative analysis of suspicious items.This product is primarily used for drug interdiction,Security screening,Screening of suspected explosive substances,Used for temporary security checks in various scenarios.During screening for suspected drugs or explosives,Combining fluorescence quenching with Raman spectroscopy,Achieve trace detection and confirmation of drugs and explosives.
      

      At large-scale events,Postal services,Customs,Checkpoints,In security screening scenarios,Fluorescence-Raman technology integration,Complementary strengths and weaknesses,Perfectly achieves detection of flammable/explosive items in temporary security checks(Such as alcohol,Gasoline,Kerosene,Diesel, etc.),Chemical agents,Toxic and hazardous chemicals,Suspected explosive substances,On-site rapid identification and precise qualitative analysis of drugs,Provide on-site guidance for rapid handling of suspicious items.Device database can be expanded anytime,Lightweight,Portable.
