Clarity Control Module VICI VALCO VALVES AS AUTOSAMPLER

Importance of the topic

Multiposition sampling valves are critical in automated chromatography workflows, enabling precise sample introduction, synchronization with analysis methods, and improved throughput in industrial and research laboratories. Integrating VICI Valco valves as autosamplers within the Clarity chromatography station reduces manual intervention, enhances reproducibility, and supports high-throughput QA/QC processes.

Objectives and Overview

This document provides a comprehensive guide to configuring VICI Valco multiposition valves as autosamplers controlled directly from the Clarity software environment. It outlines system requirements, installation and communication setup, method configuration, real-time monitoring, report integration, and troubleshooting procedures.

Methodology and Instrumentation

• Hardware components: VICI Valco multiposition microelectric or universal actuator (RS-232 or USB) and DataApex Clarity Control Module (p/n A26).
• Communication interface: Serial cable (DB9F to 3-pin, VICI Valco p/n I-22697 or DataApex p/n SK17); parameters set at 9600 baud, 8 data bits, no parity, 1 stop bit. USB connectivity uses FTDI virtual COM drivers.
• Software configuration: In Clarity’s System Configuration, add the UNI control module, select the correct COM port, use AutoDetect to verify device connection, assign to the instrument tab, and configure digital I/O lines for external start and ready signals.

Main Results and Discussion

• Automated valve positioning: Home position definition, loop fill delay, and return-to-home delay ensure precise timing of valve actuation relative to chromatographic runs.
• Device Monitor feature: Displays real-time current and target positions, enabling manual valve control when the system is idle.
• Report integration: All autosampler parameters, including custom device names and timing settings, are recorded in method reports for full traceability.

Benefits and Practical Applications

• Enhanced throughput: Automated sample selection minimizes downtime between injections.
• Improved reproducibility: Consistent valve actuation and delay intervals ensure uniform sample handling.
• Flexibility: Supports up to 32-position valves and can be adapted to a wide range of process analyzers and laboratory QA/QC scenarios.

Future Trends and Potential Applications

Future developments may include direct integration with mass spectrometers, networked remote diagnostics, advanced scripting for conditional sampling protocols, and IoT-enabled autosampler modules for real-time, distributed process monitoring in Industry 4.0 environments.

Conclusion

The VICI Valco valve autosampler solution in the Clarity software provides a fully integrated, reliable, and flexible approach to automated sample handling. Proper setup of the DataApex UNI control module ensures robust communication, comprehensive method integration, real-time monitoring, and detailed reporting to support high-throughput analytical workflows.
