The Connected Laboratory for LC and LC-MS Workflow Automation

Importance of the Topic

Reliable and reproducible sample preparation is essential for high-performance LC and LC-MS analyses. Automation reduces manual errors, enhances throughput, and ensures data integrity, enabling laboratories to maintain consistency across complex workflows and comply with regulatory standards.

Objectives and Study Overview

This whitepaper presents the Waters Connected Laboratory solution designed to streamline LC and LC-MS workflows. Key components include the Andrew+ robotic pipetting system, the OneLab cloud software environment for protocol design and management, and Pipette+ electronic pipettes for guided liquid handling.

Methodology and Instrumentation Used

The approach integrates intuitive software wizards with modular hardware to support manual, guided, and fully automated sample preparation.

• Software: OneLab cloud-native platform for drag-and-drop protocol creation, execution, and traceability.
• Robotic system: Andrew+ intelligent liquid handling robot for reproducible and traceable pipetting.
• Electronic pipettes: Pipette+ devices for guided and precise single- and multichannel dispensing (0.2 µL–10 mL).
• Connected tools: Vacuum extraction modules, heating/cooling units (0 °C–99 °C), mixers, shakers, and magnetic bead separators.

Main Results and Discussion

Deployment of the Connected Laboratory demonstrates significant improvements:

• Reproducibility: Centralized protocol management reduces user-to-user and lab-to-lab variability.
• Accuracy: Automated dilution, normalization, and volumetric precision enhance confidence in quantitative results.
• Flexibility: A modular ecosystem accommodates varying workflow complexities from simple pipetting to full robotics.
• Connectivity: Seamless integration of devices and electronic documentation ensures consistent execution and audit trails.
• Safety and ergonomics: Robotics minimize repetitive strain injuries and support operation in biosafety cabinets.

Benefits and Practical Applications

Automated sample preparation accelerates method development, lowers the risk of manual errors, and frees analytical personnel to concentrate on data analysis. Organizations gain faster time-to-result, improved compliance with EU Annex 11 and 21 CFR Part 11, and robust electronic records for audits.

Future Trends and Opportunities

Future advancements may include AI-driven workflow optimization, real-time performance analytics, enhanced device interoperability, and expanded remote monitoring capabilities. These developments will support higher throughput, adaptive method refinement, and greater operational efficiency in regulated environments.

Conclusion

The Waters Connected Laboratory unifies software and hardware to deliver precise, reproducible, and traceable LC and LC-MS sample preparation. Its intuitive design and modular architecture make it accessible across research, quality control, and industrial labs, driving productivity and regulatory compliance.
