The market demands
Metals, minerals, and inorganic compound
markets demand high-quality products.
But all solid materials are influenced in
their reactivity and mechanical properties
by certain specific chemical elements,
either positively or negatively. Therefore
there is a need for continuous and rapid
monitoring of spe­cific elements, from raw
material to finished products. User specifications, standards and product liability
all demand the highest level of product
monitoring, including ppm levels in:
Metal production and processing
Automotive industry
Chemical and pharmaceutical industry
Steel plants and other demanding metal industries require
high-perfomance ON/H analysis
Coal processing and oil refinement
Semiconductor
and many other industries.
Besides production control, research
and development of new materials is of
particular significance.
Bruker Elemental analyzers throughout
the world optimize control and assurance
of precision manufacturing through highly
accurate measurements, short analysis
times, highly reliable operation and user
friendliness. The analyzer with integral
processor and external PC for control and
evaluation, as well as the peripheral
equipment (e.g. balance, printer, extension modules), can be set up individually.

Analysis screen
Analysis Software
The analysis software of the
G8 GALILEO is structured clearly and
simply. All tasks to be performed by
software are clearly divided
into four different screens.
In order to have the most important
information available in one view, we
separate all necessary information into
four major screens. Three of those
four screens: Analysis screen, Program Settings and Statistics screen
are shown at the right side of this
page. Changing views or entering
information can be done by mouse
or keyboard. Shortcuts support the
mouse-less use of the software.
You can perform all analyses and signal performance tasks on the Analysis
screen. Current signal data will be presented graphically and the final results will
be shown numerically. The results of the last five analyses are shown simultaneously. Even at later times you can call up any information in the result manager
on this screen.
Program settings
The software supports various brands
of balances. Sample weight can be
entered manually or transferred
directly from the balance to the
ONH analyzer via serial interface.
An optional autoloader for either 20 or
40 samples is available for automated
operation.
At your service
Program settings allows you to define all necessary analysis conditions, such
as parameters for temperature and time for one specific application; which can
be stored as user-defined names. It is easy to call up different configurations for
each application.
Statistics
For further information regarding the
G8 GALILEO or any of our other
instruments please call our local office in
your region. We will be glad to assist you
with all questions you might have.
The Statistics screen shows the evaluation of all analyses: Values for average,
standard deviation, variance, variance coefficient, minimum and maximum values
will automatically be displayed on the screen. An attached printer allows the easy
printout of all data.
Gas flow diagram
The carrier gas
The appropriate carrier gas ( Helium,
Nitrogen or Argon ) for each application
is guided into the selected furnace after
passing through pre-cleaning reagents
and adjustable flow meters.
Using the integrated impulse furnace,
the sample is melted and Oxygen, along
with Nitrogen or Hydrogen, is analyzed
simultaneously. The analysis temperature
is user-defined and regulated automatically with temperatures up to 2500°C.
The optical pyrometer allows an optimized regulation of temperature during melting process and analysis. Alternatively,
other furnace controls, such as current
control or power control are available for
analyzing the sample.

Over the years we have developed many methods for specific
customer requirements in our application laboratory. We are
pleased to offer you our support. Furthermore, new applications are constantly developed in cooperation with our
customers. Due to modular structuring, software adaptations
and instrument modifications are possible depending on each
customers’ specific requests.
The G8 GALILEO can be easily and quickly
converted by software from the simultaneous analysis of Oxygen and Nitrogen
to the determination of Hydrogen. As an
option, an external furnace for determination of diffusible Hydrogen can also be
implemented.
For diffusible Hydrogen applications,
different models of external furnaces are
available depending on the application.
Samples up to a diameter of 29 mm (1.1”)
and a length of 100 mm (4”) can be analyzed using the infrared furnace. This is of
particular importance to the examination
of welding seams according to EN ISO
3690. Since diffusible Hydrogen certified
reference materials are not available, the
G8 GALILEO offers an optional gas calibration device capable of producing a 10-point
calibration curve.
The detection system
The detection system consists of a sensitive infrared detector for measuring Oxygen,
with the option of a dual-range configuration, and a thermo-stabilized thermal
conductivity cell for Nitrogen and Hydrogen
detection. The measuring range is automatically selected and assures that the optimal
signal will always be evaluated. All interfering components are filtered by reagents
prior to reaching the detector systems. An
optimized nozzle always maintains the flow
of the carrier gas on a stable level.

Working Principle
Impulse furnace
Fusion extraction is achieved in a graphite
crucible. The analysis is controlled either
by temperature, current or power. The
temperature is constantly measured by an
inertia and contact-free optical sensor,
assuring the accurate control of sample
temperature throughout the analysis.
The design of the sample port allows
the analysis of pieces, chips and drillings
without additives. The built-in optical
pyrometer measures and regulates the
real temperature of the crucible,
maintaining constant analysis conditions
during the analysis cycle.
Oxygen and Nitrogen analysis is widely
used in the steel industry, where small
amounts of these elements can sig-nificantly affect product characteristics.
Maintaining the quality of steel within
production tole­rances requires rapid and
accurate Oxygen and Nitrogen analysis. Hydrogen has a severely negative
influence on all mechanical properties of
steel, especially due to pore formation and
hot fracture sensitivity and is therefore
removed by out-gassing, vacuum melting
or vacuum casting.
Cleaning system and automatic
crucible loading system
Hot extraction for the determination of
diffusible Hydrogen takes place in an
external furnace with a quartz tube.
The G8 GALILEO is available as a singleelement analyzer or in other element
configurations.
An integrated cleaning system for the
impulse furnace, as well as an automatic
crucible loader, is available as an option.
Crucibles
Different combinations of crucible
carriers and crucibles permit simple
adaptation for different applications.
