Clarity Control Module SPARK ENDURANCE

Significance of the Topic

The integration of the Spark Holland Endurance autosampler with Clarity chromatography software streamlines sample handling, enhances method reproducibility, and ensures complete recording of instrument parameters within chromatographic data. Direct serial control reduces manual intervention, improves synchronization with HPLC systems, and supports rigorous QA/QC workflows in analytical laboratories.

Aims and Overview of Configuration Manual

This manual provides step-by-step instructions for installing and configuring the Spark Endurance Control Module within the Clarity environment. It covers hardware wiring, software setup, method definition, report generation, and troubleshooting to enable direct automated control of the autosampler and seamless data acquisition.

Utilized Methodology and Instrumentation

• Spark Holland Endurance autosampler (standard or Micro Endurance model).
• Clarity chromatography station with AS Control Module (p/n A26).
• Serial straight DB9F–DB9M cable for RS-232 communication.
• Free COM port on PC or MultiCOM adapter for multiple serial devices.
• Clarity System Configuration: adding Endurance module, assigning COM port, setting device ID (20–29), and mapping start/ready digital I/O.
• Hardware Configuration dialog for option detection (tray cooling, SSV, ISS valve, plate feeder).

Main Features and Discussion

The manual divides method setup into six key areas:

• Injection & Wash: Selection between user-defined program or modular steps (timebase, mix, injection, wash); control of injection modes (Partial Loopfill, Full Loop, μl Pick-up), analysis time, flush volume and wash routines.
• Timebase: Programming of up to five digital outputs (Aux1–4, SSV, ISS-A, code output) with time-based HIGH intervals synchronized to analysis time.
• Mix: Pre-injection sample preparation via aspirate, dispense, wash, wait and repeat commands, with defined volumes, speeds and heights.
• User Program: Single-table definition of all sampler operations (valve switching, syringe actions, compressor control, markers, digital outputs) for complex protocols.
• System: Global parameters including loop volume, syringe size and speed, scale factor, plate type and orientation, tray cooling temperature, air segment usage, output reset, alarm buzzer, skip-missing-vial logic and headspace pressure.
• Vials: Definition of transport vial range for μl Pick-up mode to ensure continuous row of solvent reservoirs.

Benefits and Practical Applications

• Automated, reproducible sample preparation and injection protocols embedded in chromatogram metadata.
• Flexible method design: from simple loop injections to advanced multi-step mixing and valve switching procedures.
• Improved synchronization with LC systems via external start triggers and digital I/O mapping.
• Enhanced reporting: inclusion of full autosampler settings in method and sequence reports.
• Comprehensive troubleshooting support through communication logging (COMMDRV.INI).

Future Trends and Potential Applications

Emerging developments may include integration of autosampler control within cloud-based LIMS, advanced robotics for plate management, expanded valve arrays for multidimensional separations, and nano-scale sample handling. Remote monitoring, AI-driven method optimization, and high-throughput workflows using 384-well plates will further accelerate analytical productivity.

Conclusion

The Spark Endurance Control Module for Clarity provides robust, fully programmable serial control of autosampler functions, delivering seamless automation and detailed method documentation. Its modular architecture supports both standardized and custom protocols, meeting diverse needs in pharmaceutical, environmental, food safety, and research laboratories.
