Bruker® G8 GALILEO

CS/ONH-Analysis (CS/ONH)

Bruker® G8 GALILEO

With the G8 GALILEO analyzers, Bruker is the only company to offer fully integrated ONH solutions combining the benefits of multiple dedicated systems without any analytical compromise or technical limitations. 


Inert gas fusion analysis

The amount of O, N and H sometimes changes considerably along the entire process chain, from the production of raw materials to the completion of the finished product. Similar concern applies to argon inclusions, introduced at trace level during metal powder production by atomization that will remain in the final product.

Acquiring kinetic information about diffusible hydrogen and its damaging mechanisms are further examples of developing products like the new generations of high strengths steels, materials suitable for hydrogen storage, or biomedical implants with the same concern.

Iron, Steel, Cobalt, Nickel, Ferroalloys

The G8 GALILEO  combines ease-of-use and robustness to deliver quick and accurate results on oxygen and nitrogen results for quality and process control adjustments. Determining the amount of oxygen and nitrogen is critical for the steel making process – including final alloy adjustment with ferroalloys and production of nickel or cobalt-based alloys.

Copper Production

With a low cost of ownership and high reliability thanks to the Smart Molecule Sequence, the G8 GALILEO analyzes oxygen with high reliability – even offering precise simultaneous oxygen and hydrogen analysis using the dual element configuration. The level of residual impurities, especially oxygen, is the most important factor when grading the quality of copper. High oxygen levels increase the tendency for hydrogen embrittlement and intergranular failure.


Titanium| Zirconium| Other Refractory Metals

Low density, high strength alloys with excellent corrosion resistance such as titanium – combined with aluminum, vanadium, or molybdenum – are typically used in space, aviation, military, nuclear, biomedical and other demanding applications. The G8 GALILEO can test the oxygen and nitrogen content as well as hydrogen content to check for hydride precipitation before the subsequent cracking becomes an issue.


Metal Processing

The G8 GALILEO delivers essential knowledge about the chemical material composition of the metal processing tasks used in aviation, aerospace, automotive, biomedical, electronic and other industries. Whether the metal is stainless steel, aluminum, copper, nickel, titanium, zirconium or special metal alloys, the G6 LEONARDO is up to the task.


Aluminum | Magnesium

With the unique FusionControl and SampleCare, the G8 GALILEO is the ideal quality control tool for the aluminum industry where oxygen and hydrogen are present in the production and processing of reactive light metal. Oxygen can form insoluble, refractory inclusions while hydrogen dissolved in liquid melt can be trapped during solidification and create hydrogen-filled blisters and voids.


Magnetic Materials

The G8 GALILEO is an easy-to-use tool with great ROI for process control of oxygen – which can reduce magnetic efficiency – and hydrogen which is both necessary to the manufacturing process and potentially problematic. Rare earth metals, such as the sintered Nd-Fe-B magnets show a high tendency to absorb hydrogen which can cause fatal hydrogen embrittlement.

Powder Metallurgy | Additive Manufacturing

The ready-to-use G8 GALILEO can process high purity materials with strictly defined particle properties such as the metal powders that are used in additive manufacturing and other powder metallurgical processes where large specific surface leaves them susceptible to oxidation or moisture aging during the production chain.

Bruker® elemental analyzer for glass and ceramics

Glass | Ceramics

The G8 GALILEO is an excellent tool for the fast analysis of oxygen, nitrogen, and hydrogen in raw materials, in-production products and final products. The unique properties of glass and ceramics are influenced in fundamental ways by the presence of oxygen, nitrogen, or hydrogen during process or in the final product. Whether needed for high performance ceramics in electronics or metal cutting or refractory oxides, nitrides, or carbides the G8 GALILEO delivers.

Welding | Allied Processes

Bruker’s unique G8 GALILEO IR is supported by ISO3690 and AWS A4.3 to enable rapid assessment of diffusible hydrogen levels introduced during welding. Because of its speed, the GALILEO enables pre-welding experiments on test samples – helping the welding industry avoid costly failures.


Thermal Desorption Mass Spectrometry

TDMS with temperature ramps provides kinetic information about trapping-energy of hydrogen within a metal structure giving terms like diffusible, weakly or strongly trapped, and chemically-bound hydrogen a direct correlation with supplied activation energy. The G8 GALILEO MS can analyze hydrogen or isotopes like deuterium at concentrations of a few ng/g for precise mechanism investigations of alloys suitable for hydrogen storage.
