Thermo Scientific DFS™ High-Resolution Magnetic Sector GC/MS System, advanced gas chromatography-mass spectrometry platform with high-resolution magnetic sector analyzer for environmental analysis, food safety testing, pharmaceutical research, forensic toxicology, and complex industrial chemical applications.

Key Features

  • Magnetic Sector High-Resolution Analyzer

    • Double-focusing magnetic sector delivering resolution >60,000 (10% valley) and mass accuracy better than 2–5 ppm.

    • Mass scan range: 2 to 6,000 m/z.

    • Linear dynamic range >5 orders of magnitude with scan rates from 0.1 to 10,000 Da/sec.

    • Multiple scanning modes: voltage scan, magnet scan, Multiple Ion Detection (MID/SIM), and Multiple Reaction Monitoring (MRM).

  • Unmatched Sensitivity for POPs/Dioxins

    • Achieves signal-to-noise (S/N) ratio ≥ 200:1 (peak-to-peak, 4σ) for 20 fg of 2,3,7,8-TCDD on column.

  • Regulatory Compliance and Robust Software Tools

    • Fully compliant with global methods (EPA 1613, 1668, 1614; EU, JIS, etc.) for dioxin, PCB, and PBDE analysis.

    • DFS-specific software: SmartTune™ for optimized tuning and TargetQuan™ for isotope-dilution quantitation.

    • Optional DualData XL module nearly doubles sample throughput.

  • Operational Convenience & Stability

    • Constant mass calibration per run using lock-mass ensures reproducible data.

    • Ventless ion source exchange and separable source housing reduce maintenance downtime.

  • Compact Footprint & Quiet Operation

    • Compact system with low noise and low power consumption.

    • Integrated vacuum system with turbo-molecular and rotary pumps.


Applications

  • Dioxins, PCBs, PBDEs, and other POPs analysis (EPA and EU compliance).

  • Environmental testing in soil, water, air, and biological samples.

  • High-sensitivity food safety and clinical research.

  • Certified data generation for regulatory laboratories.
