Frequently asked questions (FAQs)

How does the DFS system handle regulatory compliance and method support?

The Thermo Scientific DFS Magnetic Sector GC-HRMS System is explicitly designed for compliance with major official methods for dioxins/POPs, including US EPA 1613, 1668, 1614, EU EN 1948, JIS K0311/K0312, etc.

It provides features such as lock‐mass trace monitoring (to ensure instrument stability during runs) and log files documenting mass resolution during each analysis.

Software packages (e.g., DFS SmartTune, DFS TargetQuan) support isotope-dilution quantification workflows, LOQ/LOD calculation, regulatory-compliant reporting.

What are the key performance specifications of the DFS Magnetic Sector GC-HRMS system?

Key performance specs of the Thermo Scientific DFS Magnetic Sector GC-HRMS System include:
• Resolution > 60,000(10% valley)
• Mass range 2-1,200 Da at full accelerating voltage (for higher masses the accelerating voltage can be lowered)
• Sensitivity (EI GC/MS): >200:1 for 20 fg 2378TCDD at m/z 322, R = 10,000, S/N=PtP 4SDLarge-volume ion source, high-capacity turbo molecular pump for robust sensitivity.

Which applications and sample types is the DFS Magnetic Sector GC-HRMS well suited for?

The Thermo Scientific DFS Magnetic Sector GC-HRMS System is well suited for:
• Dioxins and furans in environmental samples (soil, sediment, air, fly‐ash) and in food/feed matrices, low-level of dioxins and POPs in biological samples (e.g., human blood)
• PCBs, PBDEs, other persistent organic pollutants requiring femtogram-level detection.
• Challenging matrices with heavy interference burden (e.g., high sulphur fly ash, squalene-rich samples) where high resolution and matrix-tolerance are crucial.

How does the DFS Magnetic Sector GC-HRMS system differentiate itself from standard quadrupole GC-MS or GC-MS/MS systems?

The Thermo Scientific DFS Magnetic Sector GC-HRMS System is a high-resolution gas-chromatography-mass-spectrometry (GC-HRMS) system built around double-focusing magnetic sector technology, specifically designed for ultra-trace measurement of dioxins, persistent organic pollutants (POPs), PCBs, PBDEs and similar analytes. It helps solve the challenge of extremely low-level (femtogram) quantitation in complex matrices where conventional quadrupole or even GC-MS/MS systems may struggle with resolution, sensitivity or regulatory compliance.

What problem does the DFS Magnetic Sector GC-HRMS help solve?

Features of the Thermo Scientific DFS Magnetic Sector GC-HRMS System include:
• The use of a double-focusing magnetic sector analyzer (ion separation in space, mass‐independent resolution across the mass range) gives significantly better selectivity and robustness in complex matrices.
• Exceptionally high sensitivity
• Full compliance with worldwide official regulatory methods (EPA, EU, JIS) for dioxins/POPs, meaning it is validated for those stringent workflows—something many general-purpose GC-MS systems are not.
• Built for high throughput and robustness in routine quantitative labs, including large-volume ion source and ease of maintenance.
• Possibility for Dual GC configuration allowing maximum flexibility and productivity.
• Use of reference gas to deliver quality criteria for sample preparation, according to official methods (e.g., EPA 1613)
