times better signal to noise ratio
As UV-absorption is much more efficient than IR absorption, HighSense SO₂ detection delivers 10 times better S/N ratio, 5 decades of linear dynamic range with umost stability not affected by temperature variations.

Versatility for research combined with industry proven reliability

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.

Why do I need combustion analysis?

When time to result matters, while accuracy must be granted in the first shot, with minimum sample preparation, combustion analysis is irreplaceable for the analysis of light elements. These are difficult or impossible to measure by direct spectroscopic methods, especially when embedded in difficult matrices. E.g. the G4 ICARUS Series 2 delivers accurate results even in grey cast iron, where carbon is unevenly distributed in form of graphite clusters, because it applies a volumetric method - analyzing the entire sample.
