Agilent Resolve Handheld Raman Spectrometer

Overview

The Agilent Resolve Handheld Raman Spectrometer is an engineered solution for field-deployable, non-invasive chemical identification under operational constraints typical of emergency response, CBRN defense, law enforcement, and border security environments. Unlike conventional surface-only Raman systems, Resolve employs Spatially Offset Raman Spectroscopy (SORS)—a patented optical configuration that enables spectral acquisition through multiple layers of non-metallic, light-scattering barriers including opaque plastics, colored glass, cardboard, paper, woven polypropylene sacks, and laminated packaging. This capability eliminates the need to open suspect containers—preserving evidentiary integrity, minimizing operator exposure, and mitigating ignition risks associated with sensitive energetic materials. The instrument operates on a robust 830 nm near-infrared excitation source (475 mW max), optimized to suppress fluorescence interference while maintaining sufficient photon flux for high signal-to-noise ratio spectra from concealed samples. Its ruggedized, IP67-rated enclosure ensures reliable performance in rain, dust, extreme temperatures, and physically demanding scenarios—making it suitable for EOD technicians, hazardous materials response teams, and customs screening personnel operating under full PPE.

Key Features

• SORS-enabled through-packaging analysis: Identifies solids, powders, and liquids inside sealed, non-metallic containers without physical contact or sample preparation.
• Triple-mode operation: Switches seamlessly between through-packaging SORS, direct surface Raman, and dedicated glass bottle mode for transparent vials.
• Rugged ergonomic design: Large tactile buttons, glove-compatible interface, and balanced weight distribution (2.2 kg) facilitate one-handed use with chemical-resistant gloves and respirators.
• Integrated safety architecture: Low-risk optical path minimizes thermal deposition on sensitive explosives; laser shutter and interlock mechanisms comply with IEC 60825-1 Class 3B requirements.
• Modular connectivity: Standard USB 2.0 data transfer; optional Wi-Fi module enables remote triggering and real-time spectral streaming during high-risk standoff operations.
• Field-upgradable spectral libraries: Three tiered library options (Standard, Toxic & Hazardous Materials, Comprehensive) updated biannually; includes explosives precursors, TICs, CWAs, NPS, pharmaceutical adulterants, and consumer chemicals.

Sample Compatibility & Compliance

Resolve delivers consistent identification performance across heterogeneous sample forms—including crystalline solids, amorphous powders, viscous liquids, suspensions, and layered mixtures—without dilution, filtration, or solvent extraction. It supports analysis of substances contained in HDPE, PET, polycarbonate, brown glass, corrugated cardboard, kraft paper, and burlap—materials commonly encountered in illicit trafficking, industrial accidents, or battlefield caches. The system adheres to international standards relevant to portable analytical instrumentation: mechanical durability per MIL-STD-810G, ingress protection certified to IP67, and electromagnetic compatibility tested to EN 61326-1. For regulated environments, Agilent Command software provides role-based user authentication, electronic signatures, and configurable audit trails aligned with FDA 21 CFR Part 11 and ISO/IEC 17025 documentation requirements.

Software & Data Management

Agilent Command is a centralized instrument group management platform enabling fleet-wide spectral library deployment, firmware updates, measurement protocol standardization, and secure data export. Users can curate custom libraries using reference spectra acquired in-house or imported from external sources (e.g., ASTM E1840, NIST SRM databases), then assign them to individual Resolve units or logical groups. All spectral acquisitions are timestamped, geotagged (when GPS-enabled), and stored with full metadata—including laser power, integration time, offset distance, and environmental sensor readings (optional). Raw and processed spectra export in industry-standard JCAMP-DX format, ensuring interoperability with third-party chemometric tools such as MATLAB, Python (scikit-learn), or commercial multivariate analysis suites.

Applications

• Hazardous Materials & CBRN Response: Rapid classification of unknown threats behind barriers—critical for incident stabilization, evacuation planning, and decontamination triage.
• Explosives Detection: Discrimination of improvised explosive devices (IEDs), military-grade compositions (e.g., RDX, PETN), and commercial blasting agents—all within 60 seconds and without container breach.
• Narcotics & Forensic Screening: Identification of controlled substances, cutting agents, synthetic cannabinoids, and novel psychoactive substances (NPS) at ports of entry, correctional facilities, or clandestine labs.
• Industrial Safety & QA/QC: Verification of raw material identity, detection of counterfeit pharmaceuticals, and confirmation of cleaning validation residues in GMP-compliant manufacturing settings.
• First Responder Triage: Integration into mobile command vehicles or drone-deployed platforms via Wi-Fi for scalable, low-exposure threat assessment in mass casualty or urban search-and-rescue scenarios.

FAQ

Does Resolve require sample preparation or consumables?
No. Resolve performs non-contact, non-destructive analysis without solvents, swabs, calibration standards, or disposable components.
Can Resolve identify substances inside metal containers?
No. SORS requires optically transmissive barriers; metallic or conductive packaging blocks Raman signal transmission and is incompatible with the technique.
How often are spectral libraries updated, and how are updates delivered?
Library updates are released biannually and deployed via Agilent Command software—either over local network or offline USB transfer.
Is Resolve compliant with FDA 21 CFR Part 11 for regulated laboratories?
Yes—when configured with Agilent Command’s audit trail, electronic signature, and user permission modules, Resolve supports Part 11–aligned data integrity practices.
What training and technical support is available post-purchase?
Agilent provides on-site operator certification, application-specific workshops, and ongoing spectral interpretation support through its global network of field application scientists.
