Complete sample preparation workflow solution

Significance of the Topic

Efficient and reliable sample preparation combined with advanced gas chromatography-mass spectrometry workflows underpins high-quality analytical results across environmental, food safety, pharmaceutical and industrial applications. Removing matrix interferences and employing selective detection are essential to achieve sensitivity, robustness and reproducibility in routine and high-throughput laboratories.

Objectives and Study Overview

This whitepaper outlines an integrated solution that automates sample extraction, SPE cleanup, GC-MS or GC-MS/MS analysis and data processing to streamline workflows, reduce hands-on time, minimize solvent use and enhance overall laboratory productivity.

Methodology

The proposed workflow comprises three main stages:

• Automated extraction of solids and semisolids using Accelerated Solvent Extraction (ASE) for rapid, unattended sample processing
• Large-volume Solid Phase Extraction (SPE) of aqueous matrices using AutoTrace™ 280 to isolate trace organics with improved recovery and lower solvent consumption
• Chromatographic separation and detection via GC or GC-MS/MS employing high-performance columns, triple quadrupole technology and inert flow paths to achieve low detection limits and high matrix tolerance

Instrumentation

• Dionex™ ASE 150/350 Accelerated Solvent Extractor systems
• Dionex™ AutoTrace™ 280 SPE instrument
• Rocket Synergy 2 Evaporator for solvent concentration
• Thermo Scientific™ TRACE 1300 Series GC and TSQ 9000 Triple Quadrupole GC-MS/MS
• Thermo Scientific™ ISQ 7000 Single Quadrupole GC-MS system
• TraceGOLD™ GC columns
• Chromeleon™ Chromatography Data System
• TraceFinder™ Software for quantitation and screening

Main Results and Discussion

Implementation of the automated ASE and SPE modules demonstrated fast sample processing (extractions in 12–20 minutes; up to 24 unattended ASE samples; 20 mL–4 L SPE volumes) with reduced solvent usage and cost. Coupling with GC-MS and GC-MS/MS provided robust operation (NeverVent™ source, inert paths), high selectivity and sensitivity, and the capacity to monitor hundreds of analytes simultaneously. Modular GC injectors and detectors enabled quick reconfiguration, while advanced ionization sources and columns improved peak shape and reproducibility.

Benefits and Practical Applications

• Substantial time and labor savings through unattended operation and rapid module exchange
• Lower solvent consumption and waste generation reducing environmental impact and cost
• Enhanced data confidence via selective MS/MS detection and inert hardware design
• Scalable throughput suitable for QA/QC, environmental monitoring, food safety, pharmaceuticals and forensic laboratories

Future Trends and Opportunities

Ongoing advances are expected in further automation and integration with laboratory information management systems, miniaturized extraction and detection platforms, novel ionization techniques, and AI-driven data analysis for real-time decision support and predictive maintenance.

Conclusion

Integrating automated sample preparation with versatile GC-MS/MS instrumentation and advanced software creates a seamless, high-efficiency workflow that addresses modern analytical challenges, delivering reproducible, sensitive results while optimizing resource use and throughput.
