EVA3000Plus Handheld Raman Dangerous Goods Tester

Product Introduction

The EVA3000Plus Handheld Raman Dangerous Goods Tester is a portable analytical instrument designed for rapid on-site screening and identification of potentially hazardous and controlled substances. Using 785 nm laser Raman spectroscopy, it analyzes samples in solid, powder, liquid, and aqueous solution forms, supporting security inspections and field investigations. Its integrated sampling, spectral acquisition, database searching, and similarity-matching functions deliver results within seconds under suitable testing conditions. The device features a built-in database of approximately 200 contraband entries, a 5-inch high-definition touchscreen, an 8-megapixel camera, and GPS, 4G, Wi-Fi, and Bluetooth connectivity. With its lightweight handheld design and IP65-rated enclosure, the EVA3000Plus is suitable for mobile screening applications in security, customs, law enforcement, and hazardous-material inspection.

Working Principle

The EVA3000Plus uses Raman spectroscopy to characterize the molecular composition of a sample. A 785 nm laser illuminates the target, and a small portion of the scattered light undergoes an energy shift caused by molecular vibrations. This Raman-scattered light is collected by the optical probe, filtered to suppress Rayleigh scattering, and analyzed to generate a Raman spectrum.

The instrument's software compares the measured spectrum with entries in its internal substance database and evaluates spectral similarity to provide a preliminary identification result. Compatible samples may be analyzed through suitable transparent packaging, depending on packaging materials, fluorescence, sample properties, and measurement conditions. Results should be interpreted by trained personnel, particularly when decisions involve hazardous or controlled substances.

Technical Parameters

Application Scenarios

•  Security Screening: Supports preliminary identification of suspicious powders, liquids, and other materials during security inspections.

• Law Enforcement and Field Investigations: Provides portable Raman analysis for field screening and evidence documentation.

• Customs and Border Inspection: Assists trained personnel with the screening of suspicious substances and chemical materials.

•  Chemical Precursor Screening: Supports spectral comparison of substances that may require further regulatory or laboratory examination.

• Hazardous-Material Inspection: Helps identify unknown materials for preliminary risk assessment when appropriate spectral references are available.

• Industrial and Laboratory Safety: Supports field analysis of selected chemicals and materials in compatible containers.

• Emergency Response Support: Provides rapid preliminary spectral information to assist qualified response teams in evaluating unknown substances.

Important: The instrument provides screening and spectral matching results, not definitive legal or forensic confirmation. Suspected explosives, narcotics, or other hazardous materials should be handled according to applicable safety procedures, with confirmatory laboratory testing performed when required.
