Clarity Control Module TELEDYNE FOXY R1 - R2

Significance of the topic

Automated fraction collection is a key component in preparative and analytical chromatography workflows. By precisely isolating analyte zones based on time or detector signals, modern fraction collectors improve sample purity, throughput, and reproducibility. Integration with chromatography control software further streamlines method development and data management, reducing manual intervention and error risk.

Objectives and scope of the manual

This document guides the setup, configuration, and operation of the Teledyne Foxy R1–R2 fraction collector control module within the Clarity chromatography station. It covers hardware requirements, communication protocols (RS-232 or LAN), software installation, method creation, real-time monitoring, and troubleshooting to enable seamless control from the Clarity environment.

Methodology and instrumentation

• Communication setup: RS-232 serial link or TCP/IP (port 23) via DataApex UNI Ruby driver script.
• Clarity integration: installation of LC Control license, addition of Teledyne Foxy module in System Configuration, and assignment to LC instrument tab.
• Method parameters: definition of delay volumes (detector-valve, valve-vial), fraction table rules (time intervals, volume limits, detector signals, level and slope triggers, filtering), and vial numbering behaviors (start, reset conditions, last vial handling).
• Graphical feedback: real-time display of fraction events and delay markers in Data Acquisition and Chromatogram windows.

Main features and discussion

• Direct method control: all fraction collector actions are saved in chromatogram metadata for traceability.
• Flexible trigger options: combinations of signal level and slope conditions allow precise peak-based collection.
• Filter functionality: adjustable data averaging mitigates noise in trigger detection; global bunching aligns slope evaluation.
• Vial management: automatic vial change, waste handling during rack swaps, peak-top triggered vial shifts, and overflow protection.
• Interactive control: manual Next Vial, Collect/Waste toggles, Go To Position and Resume Method functions available in Device Monitor.

Benefits and practical applications

• Enhanced workflow efficiency: centralized control reduces manual steps and sample losses.
• Improved reproducibility: software-driven timing and signal thresholds ensure consistent fraction quality.
• Data integration: fraction events embedded in chromatogram files simplify report generation and compliance.
• Versatile deployment: compatible with various detectors and flow rates, suitable for preparative HPLC, peptide purification, and QA/QC tasks.

Future trends and opportunities

• Cloud connectivity: remote method management and monitoring via web interfaces or APIs.
• Machine learning integration: adaptive trigger algorithms to optimize peak capture in complex matrices.
• Expanded LIMS interoperability: automated sample tracking and metadata synchronization across enterprise systems.
• Advanced robotics: coupling fraction collectors with automated plate handlers and analytic modules for high-throughput workflows.

Conclusion

The Teledyne Foxy R1–R2 control module in Clarity offers comprehensive automation for fraction collection, combining robust hardware communication, flexible method definition, and real-time monitoring. Its integration enhances chromatographic workflows, reduces operator workload, and ensures high reproducibility.
