CS/ONH Gas Analysis


G4 ICARUS Series 2

Clean, Fast & Efficient Combustion: ZoneProtect™

The combustion analyzer G4 ICARUS Series 2 with high frequency (HF) induction furnace and HighSense™ detection sets new standards in for a rapid and precise carbon (C) and sulfur (S) analysis in inorganic solids.

Due to their impact on the material properties, the need for fast and reliable CS analysis is not limited to iron and steel but also applies to ferrous and non-ferrous metals, their alloys, ceramics, ores, cement, limestone and numerous other inorganic solids.

  • ZoneProtect™: The patented combustion zone design utilizes a gas extraction nozzle, ensuring an optimal supply of oxygen to the sample, while liberated gases and dust particles are instantly purged through the nozzle.
  • The unique, fully automatic cleaning system with brush-free dust removal ensures simultaneous cleaning of the inline high efficiency dust filter and the gas extraction nozzle while transferring accumulated dust into the crucible for disposal.
  • HighSense™ Detection: The latest innovations in the field of high-performance light-emitting diodes (UV-LED), enabled the development of a SO₂ detector with outstanding performance: Lowest detection limits and an ultra-wide linear dynamic range are specific benefits of this technique. All Bruker detectors work without any moving parts and are equipped with integrated reference beam channels to eliminate drifts and provide utmost baseline and calibration stability.

ECOnomic Quality & Process Control for O/N/H
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.
Key Benefits:
  • FusionControl™: Ongoing contact free temperature measurement of the sample
  • SampleCare™ for IGF analysis consisting of EZDrive, water cooled sample port, high capacity dust trap, followed by efficient in-line particle filtering
  • Smart Molecule Sequence™: Direct and unadulterated measurements of all emitted gases by state of the art detectors with reference channels.
  • FUSION.ELEMENTS™: Future-save easy to use software based on Bruker’s Alaska platform

Accurate and fast diffusible Hydrogen measurements

Accurate and rapid diffusible hydrogen measurements allow you to avoid embrittlement, hydrogen-induced cracking and other costly failures.

Hydrogen-induced damage is a wide-spread and dreaded phenomenon. During welding, hydrogen is generated from the dissociation of water vapor (e.g. humidity) or hydrocarbons in the welding arc, and the molten metal can rapidly pick up hydrogen. Once in the metal, hydrogen atoms can diffuse swiftly inside the microstructure of the metal. Diffusible hydrogen causes hydrogen induced cracking (also known as cold or delayed cracking), where components fail under the influence of mechanical stress – suddenly and without prior indication. Thus, diffusible hydrogen is critical to assess because of embrittlement, hydrogen induced or assisted cracking (HIC/HAC) or hydrogen delayed fracture among other damaging effects.
