DFS Magnetic Sector GC-HRMS

Ultratrace dioxins, furans and persistent organic pollutants

DFS is a double-focusing GC-HRMS system designed for femtogram-level quantification in environmental matrices, food, feed and complex biological samples.

DFS Magnetic Sector GC-HRMS

Technical positioning

Within the isotope hub, DFS is included specifically for isotope-dilution quantification with labeled internal standards. It does not replace IRMS or TIMS for natural isotope-ratio measurements.

Platform capabilities

Resolution above 60,000 and a 2–6,000 m/z mass range
Specified sensitivity for 20 fg TCDD on-column
EI, CI, FAB and FD/FI modes
Support for official dioxin, PCB and PBDE methods

Related applications

Dioxins and furans in soil, sediment, air and fly ash
POPs in food, feed and biological samples
PCBs, PBDEs and brominated flame retardants
Regulated isotope-dilution quantification
