G6 LEONARDO: A Pre-Configured Solution for ONH Analysis

The G6 LEONARDO from Bruker is built on the inert gas fusion (IGF) principle, which involves fusing the sample material in a graphite crucible at high temperatures. The gas fusion analysis (GFA) principle is also generally labeled as melt extraction (ME) since the total oxygen, nitrogen, and hydrogen, is derived by an inert carrier gas while the sample melts.

The three non-metals—Oxygen (O), Nitrogen (N), and Hydrogen (H)—determine the service life, quality, and mechanical properties of all metallic materials. In contrast to metallic alloy components, the amount of O, N, and H occasionally varies significantly along the whole process chain, from the production of raw materials to the completion of the final product. Even when present in trace quantities, O, N, and H have a major effect on the properties of the material.

Optimized with User-Friendly Features

The G6 LEONARDO with SampleCareTM technology utilizes the dependable Smart Molecule SequenceTM for precise and robust elemental study of ONH. With its pre-calibrated standard techniques and argon carrier gas rather than helium, the G6 LEONARDO answers the requirements of industrial process and quality control for easy and economical operation.

The G6 LEONARDO can be purchased as single (O, N, or H) or dual element (OH or ON) analyzer. The analyzer is designed with preconfigured methods for regular applications like: O in copper, ON or H in steel and titanium, OH in metal powders and magnetic materials for additive manufacturing and is also relevant for other inorganic material such as ceramics and glass.

FusionControl and SampleCareTM for Highest Accuracy and Reliability

The goal of an IGF analysis is to establish the sample content of the light elements O, N, and H in the trace range with 100% accuracy. That is the reason why Bruker’s G6 LEONARDO applies the Smart Molecule SequenceTM and measures the gases released by the sample directly, absolutely unaffected, 1:1, with well-established scientific principles for reliable results. It also permits oxygen determination without extra chemicals, guaranteeing high dependability and low cost of ownership.

FusionControl — Temperature Matters

The temperature applied to the sample is the most crucial parameter for a precise analysis. FusionControl in the G6 LEONARDO avoids overheating and the forming of hydrocarbons and other unwanted byproducts. Owing to FusionControl’s precise sample temperature control, the traditional method of heating up the sample as high as possible is not needed anymore.

Highest Reliability and ECOnomics

The G6 LEONARDO incorporates SampleCareTM into oxygen, nitrogen, and hydrogen analysis to realize the maximum level of economics and robustness for industrial applications.

SampleCareTM includes:

  • High-capacity dust trap and in-line particle filtering system
  • EZDriveTM, the well-established electronic motion module for automatic and torque limited positioning of the crucible, works without the extra need for compressed air. It guarantees better electrical contact between electrodes and crucible, while guarding the crucible against deformation.
  • The sample port coupled into the water-cooled furnace safeguards delicate samples from unwanted heating and hydrogen losses for improved hydrogen results.

G6 LEONARDO – Simplicity at its Best

SampleCareTM and Smart Molecule SequenceTM including FusionControl and ready-to-use precalibrated techniques for a number of industrial standard applications make the G6 LEONARDO an ideal choice for process and quality control in key metal manufacturing and processing, powder metallurgical processes, and ceramics.
