DFS* High Resolution GC/MS

Thermo Scientific* DFS High Resolution GC/MS offers outstanding sensitivity for POPs.
The instrument offers superior sensitivity for POPs - 20 fg TCDD injected onto the column will give a S/N > 200:1. In continuation of a 50-year history in high performance magnetic sector mass spectrometers, Thermo Fisher Scientific advances this technology with the DFS double-focusing, high-resolution magnetic sector. The DFS has all the best performance of a magnetic sector MS, but it neither looks nor feels like one.

Operation as simple and straightforward as operating 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 method and sequence set-up
  • Comprehensive and flexible data evaluation and reporting

Outstanding sensitivity and specificity in a high-throughput instrument

  • Exceptional signal/noise 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 2-6000 Da
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
  • Dual TRACE* GC Ultra configuration with one TriPlus XT autosampler allows GC columns of different polarity used in one sequence: samples can be injected from one vial into two different GCs in fully automated fashion
  • Water cooled DI probe and DCI probe available

Recommended for:
  • EI/CI
  • Positive and negative ions
  • Solids probe
  • FAB
  • Other ionization and inlet techniques
