G6 LEONARDO – Highest Reliability and ECOnomics

The G6 LEONARDO with FusionControl and SampleCareTM achieves the highest level of robustness and economics for industrial process- and quality-control.

The G6 LEONARDO is based on the inert gas fusion (IGF) principle, which involves fusion of the sample material in a graphite crucible at high temperatures. The gas fusion analysis (GFA) principle is also commonly termed melt extraction (ME) since the total oxygen, nitrogen and hydrogen is extracted by an inert carrier gas when the sample melts.

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.

Optimized with user-friendly features

The G6 LEONARDO with SampleCareTM technology deploys the reliable Smart Molecule SequenceTM for robust and precise elemental analysis of ONH. With its pre-calibrated standard methods and argon carrier gas instead of helium, the G6 LEONARDO addresses the needs of industrial process and quality control for easy and cost-effective operation.

The G6 LEONARDO is available as single (O, N, or H) or dual element (ON or OH) analyzer. The analyzer comes with preconfigured methods for standard applications like: ON or H in steel and titanium, O in copper, OH in magnetic materials and metal powders for additive manufacturing and is also applicable for other inorganic material like glass and ceramics.

FusionControl & SampleCareTM for Highest Accuracy and Reliability

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 SequenceTM 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, ensuring high reliability and low cost of ownership.

FusionControl - Temperature matters

The temperature applied to the sample is the most important parameter for an accurate analysis. FusionControl in the G6 LEONARDO prevents overheating and the formation of hydrocarbons and other undesirable byproducts. Thanks to FusionControl’s exact sample temperature control, the traditional approach of heating up the sample as high as possible is no longer necessary.

Highest Reliability and ECOnomics

The G6 LEONARDO introduces SampleCareTM into oxygen, nitrogen and hydrogen analysis to achieve the highest level of robustness and economics for industrial applications.

SampleCareTM consists of:

  • EZDriveTM, the proven electronic motion module for automatic and torque limited positioning of the crucible, operating without additional need for compressed air. It ensures improved electrical contact between crucible and electrodes, while protecting the crucible against damage
  • The sample port integrated into the water-cooled furnace protects delicate samples from undesirable heating and hydrogen losses for better hydrogen results
  • High capacity dust trap and in-line particle filtering system


G6 LEONARDO – Simplicity @ its best

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.
