Thermo Scientific - DFS High Resolution
Manufactured by Thermo Scientific
Thermo Scientific* DFS High Resolution GC/MS offers outstanding sensitivity for POPs.
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.

Features of DFS High Resolution
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
