Metrohm MIRA DS Product manual

Significance of the Topic

The growing need for rapid, non-destructive chemical identification in sectors ranging from first responders and military to industrial quality control drives the development of handheld Raman instruments. The MIRA DS handheld Raman spectrometer addresses critical field requirements by combining high optical performance with robust housing and versatile sampling attachments, enabling safe, reliable identification of liquids and solids without sample preparation.

Objectives and Overview

This product manual provides a comprehensive guide to the MIRA DS platform, including its setup, operation, maintenance and safety procedures. It describes the instrument variants (Basic, Advanced, Flex), software tools (MIRA Cal DS, MIRA Cal M, HazMasterG3) and accessories, with the goal of ensuring users can perform accurate chemical analyses under diverse conditions.

Methodology and Instrumentation Used

The MIRA DS employs a 785 nm laser (<100 mW, class 3B) and Orbital Raster Scan (ORS™) sampling to average over sample heterogeneities and suppress fluorescence. A touch-screen interface controls laser power, integration time and library matching. Dedicated Smart Tips such as the Universal Attachment, Stand-off and Autofocus Stand-off optimize sampling through plastics, glass, bags or at standoff distances up to 2 m. Optional holders and interlocked vials enable safe class 1 operation for tablets and vials. Data acquisition and calibration workflows are managed via onboard menus or through Metrohm’s MIRA Cal DS desktop and MIRA Cal M mobile applications. The instrument is compatible with HazMasterG3 for chemical warfare and industrial agent identification.

Main Results and Discussion

Field evaluations demonstrate sub-minute identification of unknowns, with high spectral resolution (8–10 cm⁻¹) over a 400–2300 cm⁻¹ range and robust library matching (multiple hazard classes). ORS reduces the impact of surface roughness and particle inhomogeneity. The intelligent Universal Attachment automates content vs container discrimination for safe screening of sealed samples.

Benefits and Practical Applications

• Rapid on-site hazardous material screening and quality control
• Minimal sample handling preserves integrity and safety
• Modular accessories adapt to various containers and standoff scenarios
• Integrated software streamlines data management and reporting
• Rugged design meets MIL-STD specifications for field deployment

Future Trends and Opportunities

Advancements may include expanded spectral libraries for emerging threats, AI-driven spectral deconvolution, cloud-connected workflows for remote expert support, enhanced battery life solutions and automated robotic integration for hazardous environments.

Conclusion

The MIRA DS platform unites high-performance Raman spectroscopy with field-ready versatility, enabling fast, accurate chemical identification across a spectrum of applications. Its modular attachments, robust software ecosystem and rigorous safety features make it a valuable tool for security, industrial and environmental professionals.
