Automated Sample Handling and Analysis With NOVA: Autolab in Combination With Metrohm Liquid Handling

Significance of the Topic

Automatic liquid handling integrated with electrochemical analysis offers improvements in throughput, consistency, safety, and risk mitigation, enabling high-volume routine sample analysis.

Objectives and Study Overview

This application note demonstrates how Metrohm liquid handling devices (814, 815, 858 Sample Processors, 846 Dosing Interface, 800 Dosino, stirrers, pumps) can be integrated with Autolab potentiostats via NOVA software for automated sampling and analysis workflows.

Methodology and Instrumentation

Integration is achieved through USB connections and MSB ports. The supported devices include:

• Metrohm 814/815/858 Sample Processors (3 MSB ports)
• Metrohm 846 Dosing Interface (4 MSB ports)
• 800 Dosino, magnetic stirrers, remote interface, pumps (peristaltic, membrane), swing head

NOVA software provides graphical instrument setup, manual control panels, and scriptable commands for these devices, enabling embedding in any measurement procedure. Figures illustrate MSB port layouts and NOVA interface elements.

Main Results and Discussion

Integration is straightforward; device settings can be configured in NOVA, stored per instrument, and executed within measurement sequences. Sample preparation steps such as dosing, mixing, and pumping are automatically controlled, reducing manual interventions and errors.

Benefits and Practical Applications

• Reduced experiment duration with automated workflows
• Minimized user-related errors and contamination risk
• Enhanced reproducibility and throughput in routine electrochemical analyses

Future Trends and Opportunities

Continued development of automated lab integration will focus on expanded device libraries, intelligent scheduling, remote monitoring, and cloud-based data management. Machine learning for predictive maintenance and adaptive workflows may further enhance performance.

Conclusion

The combination of Metrohm liquid handling devices with Autolab NOVA software provides a versatile platform for automating electrochemical sample handling. This integration streamlines workflows, improves data quality, and supports high-throughput applications in research and industry.
