DFS High Resolution GC/MS
High Performance Magnetic Sector GC/MS
The Thermo Scientific DFS high
resolution GC/MS is the highest
performance, most efficient and simple
to operate magnetic sector mass
spectrometer ever built.
• Performance - Modern innovations in
ion optics, magnet and electric sector
design, provide industry leading specificity for trace target compound analysis;
whilst delivering unrivalled signal to noise
characteristics for reliable peak integration
and quantification.
• Simplicity - The DFS mass spectrometer
is simple to operate and feels like a
benchtop GC/MS. Automated tune and
mass calibration ease adoption of the
technology into the laboratory, whilst
freeing the analyst for other tasks.
• Efficiency - Lowest in class running
costs, combined with high throughput
capabilities of dual GC configurations,
significantly increase laboratory sample
capacity whilst reducing cost per sample.
DFS Mass Spectrometer
The DFS is a high resolution magnetic sector
mass spectrometer like none before. It has
been designed from the ground up to benefit
from new innovations and modern production
techniques. Cumulative advances in modern
component design and manufacture,
combine to provide the most powerful
high resolution GC/MS ever for the most
demanding confirmatory POPs analyses.
Hardware Specifications
Ion Source
The ion source has been designed with
special emphasis on sensitivity and durability
for increased productivity, low maintenance
and increased uptime.
Vacuum Interlock
The DFS mass spectrometer is equipped
with a vacuum interlock for quick exchange
of ionization volumes and filaments without
• Plug-in ion source with optimized box
design for quick exchange including
built in ion extraction lens for ease of
• Pneumatically actuated by system control
• Exchange of ion volume and filament
without venting
• Optimized long lifetime filaments for EI
and CI
• Independent source temperature control
• Simple source design - clean quickly
• Inert composition - clean less frequently
Reference Inlet
An independent reference calibrant system
that is continuously flow adjustable and can
be individually evacuated. It allows syringe
introduction of liquid or gaseous samples.
By separating the reference inlet from the
GC interface, maintainance is reduced and
uptime maximized.
• Eliminates improper manual operation
The DFS system uses the same Thermo
Scientific tuning software found on other
Thermo Scientific GC/MS & LC/MS
instruments; TunePlus™. Designed with
automation and simplicity in mind; the
tuning process, experiment and sequence
set-up is intuitive and rapid. The DFS mass
spectro-meter enables the reliable, routine
use of AUTOTUNE in all ionization modes
without restrictions, including slit control and
automated resolution settings.
Mass Calibration
Thermo Fisher Scientific invented the field
calibration method of scanning magnetic
mass spectrometers. The DFS system offers
full data system control of field calibration
The mass scale needs to be calibrated
only once. The operator can change mass
range and scan speed without the need for
recalibration. It is the same approach and
handling as known from benchtop GC/MS
• Constant mass calibration based on
magnetic field measurement
• Calibration independent of mass range,
scan speed, scan mode (including linked
scan MS/MS), ion polarity and ionization
• No recalibration required after change of
ion volume or ionization technique
The newly designed DFS analyzer has
virtually no image aberrations. It is perfectly
double focusing; employing an ultra high
precision toroidal electrostatic analyzer
and a carefully refined magnetic analyzer. This directly translates into stability and

produced by turbomolecular pumps enables
the DFS system to achieve lower detection
limits routinely.

TriPlus RSH Autosampler
Seamless Operation
The Thermo Scientific TriPlus RSH
Autosampler offers exceptional precision,
flexibility, and productivity in robotic,
sample-handling solutions. Compatible with
Thermo Scientific GC and GC/MS systems,
the autosampler sets new standards in
automation and provides advanced liquidhandling cycles that enable automated
functionality beyond traditional liquid,
headspace, and solid-phase microextraction
(SPME*) injections.
Accurate automation of a multitude of
traditionally manual tasks is enabled by a
new and innovative ATC (Automatic Tool
Change) capability. The ATC feature enables
the user to set up a sequence using up to
six different syringes, automatically loaded
by the autosampler to accurately perform
dilutions, calibrations, and sample injections.
The ability to exchange syringes for different
tasks enables high-precision sample
handling in a single, unattended sequence
prior to automated sample injection.
