G8 GALILEO for High-End Oxygen, Nitrogen, and Hydrogen Analysis

With the G8 GALILEO analyzers, XRF Scientific is the only firm to provide fully integrated ONH solutions that combine the benefits of numerous specialized systems with no analytical compromises or technical limits. The G8 GALILEO uses sophisticated sequencing to directly measure all released gases and provide true 1:1 information. No chemical modifications, mathematical adjustments, or unpublished methods are required.

FusionControl, the continuous contact-free temperature measurement of the sample, assures the correct analysis temperature, prevents the production of interfering products, and increases stability and uptime.

There are options for automatic sample and crucible handling, electrode cleaning, and automatic gas dose calibration. When equipped with the G4 PHOENIX's unique IR furnace, it delivers reliable measurements of diffusible, residual, and total hydrogen while also meeting ISO 360 and AWS A4.3 welding requirements.

Why Gas Fusion Analysis?

The mechanical characteristics, quality, and service life of all metallic materials are determined by the three non-metals: oxygen (O), nitrogen (N), and hydrogen (H). The amounts of O, N, and H can occasionally vary significantly throughout the entire process chain, from the creation of raw materials to the completion of the final product, unlike in metallic alloy components.

This also holds true for argon inclusions, which are introduced at trace levels during atomization in the manufacture of metal powder and remain in the finished product.

Acquiring kinetic information on diffusible hydrogen and its destructive processes is a further example with real-world contexts, such as the development of new generations of high-strength steels, materials appropriate for hydrogen storage, or biomedical implants.

Applications

Iron, Steel, Cobalt, Nickel, Ferroalloys

The manufacture of nickel- and cobalt-based alloys, as well as the final alloy modification through the inclusion of ferroalloys, depends on determining oxygen and nitrogen concentrations. To provide quick, precise oxygen and nitrogen readings for quality and process control in key manufacturing processes, the G8 GALILEO combines robustness with ease of use.

Metal Processing

The G8 GALILEO provides essential information about the chemical material composition for every challenging metal-processing task in the aviation, space, automotive, biomedical, electronic, and related industries. These materials include stainless steel, aluminum (Al), copper (Cu), nickel (Ni), titanium (Ti), zirconium (Zr), and other special metal compositions.

Glass and Ceramics

Refractory oxides, nitrides, and carbides are used in a variety of applications, including refractory materials in industry, high-performance ceramics in electronics, and metal cutting. The levels of oxygen, nitrogen, and hydrogen present in the process or finished product have a significant impact on the distinctive qualities of glass and ceramics. The G8 GALILEO is a superb instrument for the rapid examination of raw materials, intermediates, and final products, thanks to its sample-protection technology, FusionControl, and resilience.

Copper Production

When grading copper, the most essential quality criterion is the quantity of residual contaminants, namely oxygen. High oxygen levels increase the risk of hydrogen embrittlement and intergranular failure. Advanced sequencing ensures that the G8 GALILEO analyzes oxygen with excellent reliability and low ownership costs, while FusionControl enables precise simultaneous oxygen and hydrogen measurement in dual-element setups.

Titanium, Zirconium, and Other Refractory Metals

Titanium mixed with elements such as aluminum, vanadium, and molybdenum creates low-density, high-strength alloys with good corrosion resistance. These high-performance alloys, which are utilized in space, aviation, military, nuclear, biomedical, and other demanding applications, are impacted by their oxygen and nitrogen content, but the most important specification is the hydrogen concentration, which causes hydride precipitation and cracking. The G8 GALILEO is ready to meet the demands of these demanding sectors.

Aluminum and Magnesium

These reactive light metals are produced and processed primarily by oxygen and hydrogen. While hydrogen is dissolved in the liquid melt and confined during solidification to generate hydrogen-filled voids and blisters, oxygen forms insoluble, refractory inclusions. The G8 GALILEO is the ideal quality-control instrument for the aluminum manufacturing sector, thanks to its exclusive FusionControl and protective technologies.

Powder Metallurgy and Additive Manufacturing

High-purity metal powders with precisely defined particle characteristics are employed in additive manufacturing and other powder metallurgical procedures. Due to their huge specific surface area, they are vulnerable to “aging” due to oxidation and moisture during the production process, with oxygen and hydrogen concentration controlling both the yield rate and the quality of the final product. The demands of such new industrial applications are met by the operational G8 Leonardo.

Magnetic Materials

The use of rare earth metals is connected to the development of high-strength permanent magnets. Nd-Fe-B magnets that have been sintered have a strong propensity to absorb hydrogen, which can result in lethal hydrogen embrittlement. While oxygen reduces magnetic efficiency, hydrogen is an essential component in both the production process and the recycling of rare earth metals. For process control of both elements across all phases of manufacturing, the G8 GALILEO is a cost-effective, user-friendly instrument.

Welding and Allied Processes

Supported by AWS A4.3 and ISO 3690, XRF Scientific's unique G8 GALILEO IR enables quick evaluation of diffusible hydrogen levels introduced during welding. It helps the welding industry prevent expensive failures by enabling pre-welding experiments on test samples due to its speed.

Thermal Desorption Mass Spectrometry

Kinetic information, such as the trapping energy of hydrogen within a metal structure, can be obtained using Thermal Desorption Mass Spectroscopy (TDMS) with temperature ramps. The supplied activation energy can be directly linked to terms such as diffusible, chemically bound hydrogen, and weakly or strongly constrained hydrogen.

The special G8 GALILEO MS from XRF Scientific can detect hydrogen or isotopes such as deuterium at concentrations as low as a few ng/g. This makes it possible to conduct the exact mechanistic research required to create new alloy generations or alloys that can store hydrogen.
