Outstanding sensitivity in target compound analysis

Outstanding sensitivity in target compound analysis

Achieve outstanding sensitivity for analysis of dioxins and persistent organic pollutants (POPs) with the Thermo Scientific DFS Magnetic Sector GC-HRMS system. The DFS GC-HRMS with double-focusing system delivers ultimate mass spectrometry performance for target compound analysis. Injecting as little as 20fg of TCDD onto the column will give an exceptional signal/noise ratio (greater than 200:1). A product of 50 years of experience in developing magnetic sector MS, the DFS GC-HRMS has all the features you need for your applications.

Benefits of DFS Magnetic Sector GC-HRMS



Simple benchtop MS operation
  • Automatic tuning
  • Automatic universal mass calibration: field-based calibration, i.e. mass calibration independent of scan speed, polarity, ionization mode
  • Unattended automatic operation
  • Intuitive user interface and set-up
  • Comprehensive and flexible data evaluation and reporting
Outstanding specificity and sensitivity
  • Exceptional S/N ratio with extraordinarily low detection limit: 20fg TCDD on-column in high resolution MID mode gives S/N 200:1
  • Detection system with ±20kV conversion dynode and long-life secondary electron multiplier for efficient detection of ions
  • Lowest limits of quantitation (LOQ) for dioxins and POPs
  • Mass range of 2-6000Da
Ease of ownership
  • Fits into a small laboratory
  • Reduced power consumption
  • Quieter than many other instruments
  • Requires little installation time and ramp-up
Other key features
