DFS™ Magnetic Sector GC-HRMS

Thermo Scientific™  Related applications: Industrial Mass Spectrometry

Achieve outstanding sensitivity for analysis of dioxins and persistent organic pollutants (POPs) with the Thermo Scientific™ DFS™ Magnetic Sector GC-HRMS system. The DFS double-focusing system is the highest performance mass spectrometer ever built 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 system has all the performance you need in a package that will fit in a small laboratory.

Operation as Simple and Straightforward as a Typical Benchtop MS
  • Automatic tuning
  • Automatic universal mass calibration: Field-based calibration, i.e. mass calibration is independent of scan speed, polarity, ionization mode
  • Unattended automatic operation
  • Intuitive user interface and set-up
  • Comprehensive and flexible data evaluation and reporting
Outstanding Sensitivity and Specificity with High-throughput
  • Exceptional S/N ratio with extraordinarily low limit of detection: 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
  • Low limits of quantitation
  • 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
  • Immediately productive
Other Key Features
  • Full range of ionization modes available: EI, CI, FAB, FD/FI
  • Pneumatically actuated exchange lock for ventless exchange of ionization volumes
  • Removable ion volumes for easy source maintenance
  • Radially laminated magnet
  • High performance toroidal ESA
Recommended For:
  • EI/CI
  • Positive and negative ions
