Automated SPME-analysis Multi Fiber EXchange - MFX
Brochures and specifications | | GERSTELInstrumentation
Solid Phase Micro-Extraction (SPME) is a solvent-free extraction technique widely used for trace-level analysis of organic compounds in complex matrices. Automation of SPME enhances reproducibility, reduces manual errors and increases throughput, which is critical for high-volume laboratories and environmental monitoring.
This whitepaper describes the integration of SPME automation using the GERSTEL MultiPurpose Sampler (MPS) with Multi Fiber Exchange (MFX) and MAESTRO software control. The aim is to demonstrate fast method optimization, flexible fiber selection and continuous unattended operation for diverse analytical challenges.
SPME fibers coated with various adsorbent phases enable headspace or direct liquid extraction. The GERSTEL MPS automates sample preparation steps including fiber handling, on-fiber derivatization and internal standard addition. Thermal desorption occurs in the GERSTEL Cooled Injection System (CIS) with a septumless head for efficient analyte transfer into GC/MS. Automated fiber exchange is accomplished with MFX, minimizing mechanical stress and extending fiber life. The MAESTRO software provides a user-friendly interface for method setup, sequence control and parallel execution of extraction and analysis (PrepAhead).
Automated fiber exchange at user-defined intervals allows overnight and weekend operation without intervention, including recalibration after fiber changes. Use of multiple fiber phases improves selectivity and detection limits across a wide polarity and volatility range. Automated bake-out options ensure low carry-over and consistent blank levels. The modular system supports simultaneous analysis of air samplers, passive samplers and liquid samples.
Future developments may include integration with LC/MS platforms, AI-driven optimization of extraction parameters, further miniaturization of sample prep devices and green analytical methods. On-site and real-time monitoring workflows will benefit from portable, automated SPME systems.
The GERSTEL MPS with MFX and MAESTRO software delivers a robust, flexible and high-throughput automated SPME solution. It streamlines method development, ensures reproducible results and adapts readily to a variety of matrices and analytical demands.
