Metrohm MIRA XTR DS Product manual

Importance of Topic

The ability to perform rapid, nondestructive chemical identification at the point of need is critical for applications ranging from first responders to industrial quality control. Handheld Raman spectrometers, such as the MIRA XTR DS, provide high‐power, field‐portable analysis with advanced fluorescence rejection and container‐through identification techniques.

Objectives and Overview

This product manual defines the intended use, safety guidelines, functional description, installation, configuration, operation, maintenance and technical specifications of the MIRA XTR DS handheld Raman analyzer. It supports both Basic and Advanced models and integrates with Metrohm’s software ecosystem for instrument control and data management.

Methodology and Instrumentation

The MIRA XTR DS uses a 785 nm diode laser (class 3B), delivering up to 100 mW to excite Raman scattering. Orbital Raster Scan (ORS) optics average spatial heterogeneity and suppress background. A range of Smart Tips—direct‐contact ball probe, universal attachment, autofocus and manual stand‐off lenses, SERS substrates, tablet and vial holders—enable measurement of liquids, solids, bagged materials or samples inside containers. Data acquisition is managed by the on‐board firmware or via MIRA Cal DS (desktop) and MIRA Cal M (Android) software. Optional HazMasterG3 integration provides extended chemical agent guidance.

Main Results and Discussion

Users can select or build operating procedures that define laser power, integration time, averaging, fluorescence eXTRaction (XTR™) settings and library matching. The intelligent Universal Attachment (iUA) automatically triggers a two‐step container-and-content identification workflow. On‐board processing yields match rankings, GHS hazard classifications and mixture deconvolution. Data transfer is supported via USB mass storage or Bluetooth® to Android devices.

Benefits and Practical Applications

• First‐responder identification of unknown powders, liquids or mixtures without sample destruction
• Industrial spot checks and QA/QC of raw materials or final products
• Forensic and security screening for explosives, narcotics and chemical threats
• SERS enhancements for trace‐level detection on proprietary substrates

Future Trends and Opportunities

Emerging developments include integration of machine‐learning algorithms for spectrum interpretation, expansion of spectral libraries (e.g. real-time crowd-sourced updates), robotic mounting for remote or hazardous environments and Internet-enabled data sharing for distributed monitoring networks.

Conclusion

The MIRA XTR DS platform delivers a versatile, high‐performance handheld Raman solution optimized for on-site chemical identification. Its modular Smart Tips, robust fluorescence handling and seamless software integration support a broad range of field and laboratory applications.
