The lower electrode movement by EZDrive eliminates the need for additonal working gases, ensures an ideal contact between crucible and electrodes to provides enhanced safety and reliability.

G6 LEONARDO - ECOnomic Qualiy and Process Control by Inert Gas Fusion

Electrode Furnace with SampleCare and FusionControl
The three non-metals Oxygen (O), Nitrogen (N) and Hydrogen (H) determine the quality, service life and mechanical properties of all metallic materials. Unlike metallic alloy components, 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. Even when present in trace amounts, O, N and H have a very critical effect on the material properties.
The G6 LEONARDO is based on the inert gas fusion (IGF), which involves fusion of the sample material in a graphite crucible at high temperatures. This principle is also commonly termed gas fusion analysis (GFA) or melt extraction (ME) since the total oxygen, nitrogen and hydrogen is extracted by an inert carrier gas when the sample melts.
 
The Smart Molecule Sequence™ guarantees trustworthy results
The aim of an IGF analysis is to determine the sample content of the light elements O, N and H in the trace range with absolute accuracy. That is why our G6 LEONARDO applies the Smart Molecule Sequence™ and measures the gases emitted by the sample directly, absolutely unchanged, 1:1, with proven scientific principles for trustworthy results. It also allows oxygen determination without additional chemicals, and usage of argon carrier gas instead of helium ensuring high reliability and low cost of ownership.

Optimized with user-friendly features

SampleCareTM, Smart Molecule SequenceTM including FusionControl and ready-to-use precalibrated methods for many industrial standard applications make the G6 LEONARDO a great choice for process and quality control in primary metal manufacturing and processing, ceramics, and powder metallurgical processes.

G6 LEONARDO Applications

Iron, Steel, Cobalt, Nickel, Ferroalloys

Determining the amount of oxygen and nitrogen is critical during the steel making process, the final alloy adjustment by addition of ferroalloys but also for the production of nickel- and cobalt-base alloys. The G6 LEONARDO combines the ease-of-use and robustness to deliver fast and accurate oxygen and nitrogen results for the Quality- and Process-Control in these production processes.

Copper Production

The most important quality factor when grading copper is the level of residual impurities, primarily the oxygen level. High oxygen levels increase the tendency for hydrogen embrittlement and intergranular failure. The Smart Molecule SequenceTM, ensures the G6 LEONARDO analyses oxygen with high reliability and low cost of ownership, while precise simultaneous oxygen and hydrogen analysis is available in dual element configurations with FusionControl.

Titanium, Zirconium and other Refractory Metals

Titanium combined with elements like aluminum, vanadium, molybdenum produces low-density, high-strengths alloys with excellent corrosion-resistance. These high performance alloys used in space, aviation, military, nuclear, biomedical and other demanding applications are affected by their oxygen and nitrogen content, but the most critical specification is the hydrogen content leading to hydride precipitation and subsequent cracking. The G6 LEONARDO is prepared to address the needs of these demanding industries.

Aluminum and Magnesium

Oxygen and hydrogen play a dominant role during the production and processing of these reactive light metals. Oxygen forms insoluble, refractory inclusions whereas hydrogen, dissolved in the liquid melt, is trapped during solidification, creating hydrogen filled voids and blisters. With its unique FusionControl and SampleCareTM, the G6 LEONARDO is an ideal quality control tool for the aluminum producing industry.

Magnetic Materials

The evolution of high strengths permanent magnets is related to the application of rare earth metals. Sintered Nd-Fe-B magnets show a high tendency to absorb hydrogen, leading to fatal hydrogen embrittlement. Actually, hydrogen is a vital agent in the manufacturing process but is also during recycling of the rare earth metal, while oxygen reduces the magnetic efficiency. The G6 LEONARDO is an economic and easy-to-use tool for process control on both elements during all production stages.

Powder Metallurgy and Additive Manufacturing

Metal powders used in additive manufacturing and other powder metallurgical processes are high purity materials with strictly defined particle properties. Their large specific surface makes them susceptible to “aging” by oxidation/moisture along the production chain with oxygen and hydrogen content dominating the yield rate and product quality. The ready-to-use G6 LEONARDO addresses the needs of such emerging industrial applications.

Glass & Ceramics

From industry refractory materials to high performance ceramics in electronics or in metal cutting, refractory oxides, nitrides and carbides have a wide usage. The unique properties of glass and ceramics are influenced in fundamental ways by the level of oxygen, nitrogen and hydrogen present in the process or in the final product. With SampleCareTM, FusionControl and its robustness, the G6 LEONARDO is an excellent tool for the fast analysis of raw materials, intermediates and final products.
