PowerPack for Mira

Importance of the topic

Portable Raman spectroscopy is increasingly vital for rapid material analysis outside of traditional labs. A reliable power source is essential to maintain continuous operation in diverse environments and ensure data quality during extended field or on-site measurements.

Objectives and overview

This article presents the PowerPack, a dedicated external battery solution for Metrohm’s Mira handheld Raman spectrometers. The goal is to extend operating time, enhance ergonomics, and improve robustness for lab, field, or warehouse applications.

Methodology

The PowerPack design integrates a high-capacity rechargeable lithium battery, robust housing, and user-friendly mounting. Key design features include:

• Plug-and-play latch mechanism for quick attachment to Mira devices
• Compact, low-centered mass to facilitate single-handed use
• Durable aluminum enclosure rated IP67 for water and dust resistance

Instrumentation Used

• Mira DS and Mira P/M-3 handheld Raman spectrometers (Metrohm Raman)
• PowerPack external rechargeable battery module (25.2 Wh capacity)

Main results and discussion

The PowerPack delivers up to nine hours of continuous active use with a full charge in under three hours. Field tests demonstrate stable performance across –20 °C to 50 °C operating range. The unit adds minimal bulk (5 × 9 × 4.5 cm) and weight (~319 g), shifting the center of mass to improve screen visibility. A cost analysis shows break-even versus disposable batteries within one year of typical daily eight-hour use.

Benefits and practical applications

• Extended operating time supports all-day analysis tasks without frequent battery changes
• Enhanced ergonomics enable single-handed handling for faster sampling
• Rugged design ensures reliability in harsh or variable environmental conditions
• Cost savings and reduced waste compared to disposable battery consumption

Future trends and potential applications

Anticipated developments include higher-energy batteries, integrated charging docks in field kits, and wireless power management. The concept may extend to other portable analytical instruments, driving smarter, more sustainable field analytics.

Conclusion

The PowerPack significantly enhances the portability and endurance of Mira Raman spectrometers, enabling uninterrupted, ergonomic, and reliable operation in diverse environments. Its robust design and economic benefits position it as a valuable accessory for routine field and warehouse analysis.
