MAESTRO Software

Automated Sample Preparation and Sample Introduction

The MAESTRO software operates all GERSTEL modules and system solutions in a simple and efficient Windows environment. MAESTRO can be operated as stand-alone software, coupled (one sequence file) with Thermo Scientific Xcalibur or AB SCIEX Analyst or fully integrated with the Agilent Technologies ChemStation and MassHunter. Just one method and one sequence table runs the complete system from Sample Preparation and Sample Introduction to GC/MS or LC/MS analysis. Set-up is performed in a very simple manner: By mouse-click, requiring no special programming language or macros. MAESTRO can also import sample information from any LIMS system in CSV format to support high throughput operation.

Main Features and Advantages

  • Complete software control of all GERSTEL modules
  • Multi--sample "Prep Ahead" for maximum efficiency and sample throughput
  • Unique graphical sample scheduler window provides real-time status information and allows easy method time optimization
  • Sample prep by mouse-click; no macro programming needed
  • Unsurpassed number of sample preparation functions available
  • Extensive on-line help
  • Graphical real-time system status information
  • Can be fully integrated into Agilent ChemStation and GC/QQQ MassHunter software
  • Modular design, easy to add capabilities
  • One copy of Maestro can control up to four MPS systems
  • Real-time E-mail notification of instrument errors
  • Complete system action logfile for traceability and fast troubleshooting

Flexibility and Traceability

MAESTRO provides full flexibility by allowing an on-going analysis sequence to be modified to incorporate priority samples while keeping track of all steps in the process.

  • Priority samples can be added to the system at any point in the analysis sequence
  • LOG file and Service LOG file functions provide traceability and make trouble-shooting easier
  • Automated E-mail notification in case the system stops running. This allows prompt intervention to ensure that your samples are analyzed as planned

On-line Help Function

MAESTRO has a built-in, context sensitive on-line help function to simplify using special features, speed up parameter entry and improve overall productivity.

  • Interactive On-line Help Function
  • Context sensitive help for fast answers and recommended starting conditions
  • Easy-to-understand explanation of each function
  • Provides recommendations for parameter settingsĀ 

Maintenance Function

MAESTRO has a built-in maintenance function, simplifying maintenance planning and improving the overall operation. If the maintenance function is activated, the software will remind you to change ferrules or to perform other specified regular maintenance tasks whenever a user-defined number of injections has been reached (maintenance counter).


MAESTRO speeds up optimization of your Large Volume Injection analysis for GC by calculating the best injection parameters (pressure, injection speed, temperature and flow) based on the solvent boiling point.
