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.
• Plug-in ion source with optimized box design for quick
exchange including built in ion extraction lens for ease
of maintenance
• Exchange of ion volume and filament without venting
• Optimized long lifetime filaments for EI and CI
Ultimate confidence and robustness
Failing to determine if samples are non-compliant or toxic
can have serious consequences. You need to be sure of
your analysis and the defensibility of your data. The
DFS Magnetic Sector GC-HRMS provides robust, confident
quantitation, down to very low femtogram levels.
Exceptional productivity and flexibility
Labs face a wide array of sample loads and application
demands. To meet these needs, the DFS Magnetic
Sector GC-HRMS can be equipped with up to two
Thermo Scientific™ TRACE GCs and four GC columns.
Add the DualData XL Module to maximize sample
throughput with up to twice as many injections per unit
time compared to a single GC system. Multiple ionization
modes and probe choices provide unmatched analytical
flexibility.
• 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 and heated. It allows syringe introduction of
liquid or gaseous samples. By separating the reference
inlet from the GC interface, maintainance is reduced and
uptime maximized.
Vacuum interlock
The DFS Magnetic Sector GC-HRMS is equipped with a
vacuum interlock for quick exchange of ionization volumes
and filaments without venting.
• Pneumatically actuated by system control
• Eliminates improper manual operation
Tuning
The DFS Magnetic Sector GC-HRMS uses the same
Thermo Scientific tuning software found on other
Thermo Scientific GC/MS & LC/MS solutions; TunePlus™.
Designed with automation and simplicity in mind; the tuning
process, experiment and sequence set-up is intuitive and
rapid. The DFS Magnetic Sector GC-HRMS 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 Magnetic Sector GC-HRMS oers full data system
control of field calibration scanning.
• Low hysteresis, radially laminated H-type magnet of
special metal alloy with mass independent focal length,
deflection radius 350 mm, deflection angle 65˚
• Innovative Rogowsky magnet entrance pole pieces for
optimum sensitivity regardless of ionization method
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 systems.
• 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 technique
• No recalibration required after change of ion volume or
ionization technique
• Novel electrostatic analyzer (ESA) using a computer
optimized toroidal design for highest mass precision and
ion transmission with virtually no image errors
• All focusing and detection elements housed in a single
monoblock vacuum chamber
• Entire DFS Magnetic Sector GC-HRMS analyzer
assembled on an integrated shock mounted platform for
isolation from floor vibration
Performance characteristics

Analyzer
The newly designed DFS Magnetic Sector GC-HRMS
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
ruggedness.
• Novel ion optics design is based on the proven reverse
Nier-Johnson geometry
• Mass independent focus with uniform resolution
throughout the mass range
• Ion optics optimized for an acceleration voltage of 5 kV
• All ionization techniques operational with full acceleration
voltage
• High precision, data system controlled, continuously
variable Tantalum entrance and exit slits for fast response
and long lifetime
The specification for sensitivity, mass accuracy and
resolution are installation specification.
This means that they are demonstrated to the customer
during the installation of the DFS Magnetic Sector
GC-HRMS.
Detection system
The long lifetime noise-free secondary electron multiplier
of the DFS Magnetic Sector GC-HRMS analyzer always
provides optimal signal amplification for all ionization
modes including negative CI.
