916 Ti-Touch, 915 KF Ti-Touch and 917 Coulometer

Importance of the Topic

The demand for robust and space saving titration systems in modern analytical laboratories has grown with the need for high throughput, data integrity and regulatory compliance. Compact integrated titrators streamline routine analysis and minimize footprint.

Goals and Study Overview

This document reviews the Metrohm Ti Touch family (models 916 Ti Touch, 915 KF Ti Touch and 917 Coulometer), highlighting their design principles, functional capabilities and application scope in potentiometric, volumetric and coulometric titrations.

Methodology and Instrumentation

The Ti Touch platform integrates dosing, stirring and control in a single module and supports:

• 916 Ti Touch for potentiometric titrations (DET, MET, SET, STAT, MAT)
• 915 KF Ti Touch for volumetric Karl Fischer titrations
• 917 Coulometer for coulometric Karl Fischer titrations

Optional accessories include the 810 Sample Processor for unattended batch analysis, 800 Dosino and 805 Dosimat dosing units, 801 magnetic stirrer, 802 rod stirrer, 803 KF titration stand, intelligent electrodes (iTrodes) and tiBase data management software. Connectivity is available via USB, RS 232, Ethernet and Metrohm Serial Bus for network and LIMS integration.

Main Results and Discussion

The integrated concept delivers maximum system integration, enabling paperless operation with PDF report generation, FDA 21 CFR Part 11 compliance, real time curve display and automated electrode tests. Users benefit from no touch reagent replacement, personalizable touchscreen workflows and modular expansion with two MSB ports for dual titration stands.

Benefits and Practical Applications

The Ti Touch family enhances laboratory productivity by:

• Saving bench space through compact instrument design
• Ensuring data security and audit trails without a PC
• Supporting multiple titration modes in one unit
• Providing plug and play operation for peripherals
• Offering flexible automation with sample changers and ovens

Future Trends and Opportunities

Future developments are likely to focus on deeper integration with digital laboratory ecosystems, cloud based data archiving, AI driven method optimization and further miniaturization. Advances in smart sensors and IoT connectivity will expand remote monitoring and predictive maintenance.

Conclusion

The Metrohm Ti Touch series represents a modern approach to titration, balancing compact design, versatile functionality and regulatory compliance. It offers a scalable solution for diverse analytical challenges, fostering efficiency and data integrity in routine and advanced laboratory environments.
