G4 ICARUS Series 2 – Carbon and Sulfur by Combustion

  • Description
  • Specification


The IC4US G4 combustion analyzer with HF induction furnace and HighSense detection is a new generation instrument for fast and precise analysis of carbon (C) and sulfur (S) in solids.

The innovative design of the combustion zone uses a gas extraction nozzle to ensure optimal excess oxygen supply to the molten sample. Released exhaust gas and dust particles are immediately removed through the extraction nozzle, and its collar protects the combustion tube from splashes of liquid sample.

The unique, fully automatic cleaning system with brushless dust removal ensures simultaneous cleaning of the inline dust filter and the gas extraction nozzle while transferring accumulated dust into the crucible for disposal

. Combined with the integrated high performance dust filter with a pore size of 3 µm, ZoneProtectTM   creates unrivaled characteristics and performance:

– More efficient, faster combustion on more samples

– Excellent gas flow

– Immediate flue gas removal without further dilution for quick and clean analysis

– Eliminating splatters and minimizing dust for maximal productivity, component lifetime and analytical quality

– Brushless, silent dust removal system integrated into the combustion zone

The G4 ICARUS Series 2 is equipped with selective semiconductor detectors with no moving parts and an integrated reference beam channel.

The latest innovations in the field of high-performance light-emitting diodes (UV-LEDs) have enabled the development of an SO2 detector with exceptional performance. Because UV absorption is much more efficient than IR absorption, this results in lower detection limits suitable even for trace analysis. Furthermore, this type of gas analysis is not affected by water molecule interference or thermal fluctuations.

The new HighSenseTM platform is equipped with a dedicated reference channel that eliminates drift and ensures the highest baseline stability and calibration. The measuring cell is equipped with an inert coating to avoid the effect of “transfer” and corrosion. The result is a SO2 detector that exceeds NDIR in all respects.
