Agilent Resolve Raman

Significance of the topic

Advances in handheld Raman spectroscopy enable rapid, noninvasive identification of hazardous and illicit substances without compromising container integrity. Such capability is vital for HAZMAT response, explosive ordnance disposal, law enforcement, and border security where safety and evidence preservation are priorities.

Objectives and study overview

This summary presents the features and performance of the Agilent Resolve Raman system in three measurement modes. The study outlines its capability to identify chemicals, narcotics, and explosives through nonmetallic barriers and compares its operation to conventional handheld Raman analyzers.

Methodology

The Agilent Resolve Raman employs spatially offset Raman spectroscopy (SORS) with an 830 nm laser to detect characteristic spectral signatures through opaque and colored plastics, glass, paper, fabrics, and sacks. Measurements are performed in three modes: through-barrier scans, surface scans (line-of-sight), and vial holder scans. Each analysis completes in about one minute without sample preparation or consumables.

Instrumentation used

The handheld system features a rugged housing with IP67 protection, shock and vibration resistance, a removable nose cone for contact and noncontact scans, a large high-contrast display, and glove-friendly controls. Key specifications include an adjustable 475 mW laser, lithium-ion batteries for up to four hours of continuous use, integrated calibration checks, and customizable chemical libraries.

Key results and discussion

The Resolve Raman system accurately identifies a broad range of materials—including explosives, chemical warfare agents, narcotics, and common industrial chemicals—through sealed nonmetallic containers. Its through-barrier capability surpasses conventional Raman devices that require clear packaging, enabling safer operations and preserving evidence integrity. The intuitive interface and rapid analysis support timely decision making in field deployments.

Benefits and practical applications

• Enhanced operator safety by avoiding direct handling or opening of hazardous materials
• Improved efficiency through fast, consumable-free measurements
• Preservation of crime scene and sample integrity
• Versatile use in military EOD, law enforcement, customs screening, and industrial QA/QC

Future trends and potential applications

Upcoming enhancements may include centralized fleet management and data analytics platforms, expanded chemical libraries with emerging threat compounds, integration with remote expert support, and AI-driven spectral interpretation. Broader adoption could extend applications to environmental monitoring and forensic investigations.

Conclusion

The Agilent Resolve Raman system marks a significant advancement in field-based spectroscopy by offering safe, fast, and accurate through-barrier detection of hazardous and illicit substances. Its combination of rugged design, user-friendly interface, and versatile measurement modes positions it as an essential tool for modern security and analytical challenges.
