MAESTRO Software

Significance of the Topic

The growing complexity and throughput demands in analytical laboratories require fully integrated automation platforms. MAESTRO software addresses this need by unifying sample preparation, introduction, and analysis in GC/MS and LC/MS workflows. Its streamlined interface minimizes manual interventions, enhances reproducibility, and ensures traceability, ultimately boosting laboratory productivity.

Objectives and Study Overview

This overview examines the capabilities of MAESTRO software, highlighting how a single method and sequence table can orchestrate all steps from automated sample preparation to instrumental analysis. Key goals include demonstrating ease of use, integration with Agilent ChemStation, and tools for optimizing daily operations.

Methodology

• Core integration of GERSTEL modules with Agilent Technologies ChemStation, enabling stand-alone or fully integrated operation.
• PrepBuilder graphical function for intuitive “Sample Prep by Mouse-Click,” covering derivatization, extraction, washing, dilution, incubation, mixing, conditioning, and more.
• Intelligent sequence editor featuring fill-down, repeat, copy/paste functions, and flexible priority sample insertion.
• Graphical Scheduler for visual planning and real-time optimization of overlapping sample preparation and analysis (PrepAhead).
• Context-sensitive online help and pop-up guidance to support rapid method development.

Used Instrumentation

• MAESTRO software, running stand-alone or integrated with Agilent ChemStation.
• GERSTEL MultiPurpose Sampler (MPS) for fully automated liquid and gas handling.
• Integration with GC/MS and LC/MS systems.
• Automated module control including TDU liner exchange (ATEX), ALEX, and multiple PCH autosamplers.
• Liquid handling options: standard addition, automated weighing, mixing, heating, conditioning.
• Extraction and concentration modules: SPE, SPME, SBSE (Twister), LLE, MASE, DHS, HS-SPME.
• Thermal desorption units (TDS, TDU) and modular accelerated column heating (MACH).
• Preparative Fraction Collector (PFC) and Polaratherm for temperature-programmed LC.

Main Findings and Discussion

MAESTRO software significantly improves laboratory efficiency by:

• Controlling all sample preparation and analysis steps through one method and sequence table.
• Maximizing throughput via automated overlapping of prep and analysis tasks.
• Providing instant feedback on scheduling changes and method edits.
• Ensuring full traceability with detailed log files and automated email notifications.
• Minimizing errors through context-aware method, tray, and injector selection menus.
• Automating maintenance reminders based on defined injection counts.

Practical Benefits and Applications

This platform delivers:

• Consistent, reproducible results across workflows such as derivatization, headspace analysis, and SPE.
• Rapid method creation and adjustment using graphical tools.
• Flexible handling of priority samples at any point in the sequence.
• Support for a broad spectrum of techniques, from liquid/liquid extraction to thermal desorption and multidimensional GC.
• Improved resource utilization and reduced turnaround times.

Future Trends and Opportunities

Emerging directions include:

• Cloud-based data management and AI-driven method optimization.
• Integration of novel microfluidic and sorptive extraction technologies.
• Remote monitoring and control via web or mobile interfaces.
• Advanced scheduling algorithms for dynamic instrument sharing and priority handling.
