Installation instructions TitrIC flex II

Importance of the topic

The TitrIC flex II system offers a fully automated solution for comprehensive water analysis by combining direct measurement, titration, and ion chromatography. It rapidly determines key water quality parameters including temperature, conductivity, pH, acid capacity (p and m values), individual anion and cation concentrations, hardness, and overall ion balance. Its modular design allows seamless integration of additional Metrohm instruments for extended analytical capabilities.

Objectives and study overview

This application bulletin provides step-by-step installation instructions for the TitrIC flex II system. The goal is to guide laboratory personnel through hardware assembly, software configuration, and method setup to ensure a reliable and reproducible multi-parameter water analysis workflow under MagIC Net and OMNIS control.

Methodology and instrumentation

The analytical sequence involves:

• Sample transfer via two Pick&Place modules to 930 Compact IC Flex systems for anion and cation analysis.
• Simultaneous conductivity measurement using a 5-ring cell on Workstation 2.
• Volume dosing of 100 mL sample into a titration beaker on Workstation 3.
• Measurement of pH, temperature, acid capacity (p and m values), and hardness using W2 and W3 titration heads with dAquatrode sensors.
• Data handling and sequence control by MagIC Net (master) and OMNIS (slave) via RS-232 communication.

Key hardware components include:

• 930 Compact IC Flex ovens with Vario/Flex Basic and ONE accessory kits for eluent and regeneration setup.
• 800 Dosino and 50 mL Dosing Unit for sample and regenerant handling.
• 20 mL Cylinder Unit for titrant delivery.
• 856 Conductometer with digital measuring module.
• Inline Ultrafiltration cell for sample pretreatment.
• Sample Robot S with distributors, peristaltic pumps, and configurable titration vessels.

Main results and discussion

The installation workflow ensures correct tubing routing, pump configuration, and software device recognition. Predefined MagIC Net methods and OMNIS operating procedures automate sample processing, calibration of conductivity and pH sensors, titrant titer determination, and multi-technique analyses in a single run. Centralized data storage enables consistent reporting across all measurement channels.

Benefits and practical applications

The integrated TitrIC flex II workflow enhances laboratory throughput and data integrity by minimizing manual intervention. It is well suited for environmental monitoring, water treatment quality control, industrial process water analysis, and research settings where multiple ionic and titrimetric parameters must be assessed simultaneously.

Future trends and opportunities

Planned system enhancements include inline eluent production modules for uninterrupted IC operation, Dis-Cover lids to prevent sample evaporation, expanded sensor arrays, and cloud-based data analytics. Further developments may leverage AI-driven method optimization and remote system diagnostics to improve efficiency and reliability.

Conclusion

The TitrIC flex II system provides a robust, turnkey solution for fully automated water sample analysis. Its detailed installation guide and software templates facilitate rapid deployment, ensuring reproducible, high-quality analytical results across ion chromatography and titration techniques.
