          ZoneProtectTM ensures a clean, fast & efficient combustion

          The innovative combustion zone design utilizes a gas extraction nozzle to ensure an optimal, surplus supply of oxygen to the molten sample. Liberated combustion gases and dust particles are instantly purged through the extraction nozzle, while its collar shields the combustion tube from splatters of liquid sample.

          A unique, fully automatic cleaning system with brush-free dust removal ensures simultaneous cleaning of the inline dust filter and the gas extraction nozzle while transferring accumulated dust into the crucible for disposal. In conjunction with an integrated high efficiency dust filter with 3μm pore size, ZoneProtectTM creates unrivaled characteristics and performance:

          • More efficient, faster combustion on a wider variety of samples
          • Superior gas flow: Instant removal of combustion gases without further dilution for fast and clean analysis
          • Eliminating splatters and minimizing dust for maximal productivity, component lifetime and analytical quality
          • Vacuum- and noise-free dust removal system integrated into the combustion zone


          The G4 ICARUS Series 2 is equipped with selective solid-state detectors without any moving parts and integrated reference beam channel.

          HighSenseTM: High-performance UV-Absorption for SO2

          The latest innovations in the field of high-performance light-emitting diodes (UV-LED), enabled the development of a SO2 detector with outstanding performance. As UV absorption is much more efficient than IR absorption, this results in lower detection limits suitable even for trace analysis. In addition this kind of gas analysis is not affected by interferences of water molecules or thermal fluctuations.

          The new HighSenseTM platform comes with a dedicated reference channel to eliminate drifts and provide utmost baseline and calibration stability. The measuring cell is equipped with an inert coating to avoid “carry-over” effects and corrosion. The result is a SO2 detector that outperforms the NDIR technique in every aspect.

          Versatility for research combined with industry proven reliability

          The analytical performance gained by the combination of HighSenseTM detectors and ZoneProtectTM furnace technologies provides the analytical flexibility, performance for research while extending its proven efficiency, robustness, speed and long-term stability required in industrial environments.

          Iron, Steel, Cobalt & Nickel

          Iron, Steel, Cobalt & Nickel

          Carbon is the primary interstitial alloying element in these materials and greatly influences their properties. Sulfur is either considered a contaminant or desired additive. During the metal production and alloying a high precision on carbon and sulfur analysis is vital for an optimal production process. The G4 ICARUS Series 2 is prepared to meet and exceed demanding process control requirements on the final metal as well as on ingredients like ferroalloys and raw materials up to slags formed.

          Metal Processing

          Metal Processing

          Ores & Minerals

          Ores & Minerals

          The value of minerals and metal-bearing ores is determined by its target metal content. The sulfur level of the ore concentrate provides an estimation of the metal-in-concentrate and is used as a quality control measure, determining the efficiency of the concentration process. The knowledge of the exact carbon and sulfur levels allows the optimization of the mine operation and mineral beneficiation. The ultra-wide range of its HighSense detectors makes the G4 ICARUS Series 2 the ideal analytical addition to every mining laboratory.

          Cast Iron

          Cast Iron

          Carbon is the main alloying element in cast iron with typical levels greater 2%. Even in difficult matrices like grey cast iron, where carbon is unevenly distributed in form of graphite flakes, the G4 ICARUS Series 2 delivers accurate results because it applies a volumetric method, analyzing the entire sample. Mold powder and fluxes are also analyzed by the G4 ICARUS Series 2.



          Cement is a hydraulic binder and the main ingredient of many basic building materials, such as concrete and mortar. Quality- and Process-Control require the fast and accurate analysis of the elemental and phase composition. The G4 ICARUS Series 2 provides an easy and fast method to control the limestone and gypsum / anhydrite addition in cements by measuring carbon and sulfur.

          Glass & Ceramics

          Glass & Ceramics

          From industry refractory materials to high performance ceramics in electronics or in metal cutting, refractory oxides, nitrides and carbides have a wide usage. The unique properties of glass and ceramics are influenced in various ways by the level of carbon and sulfur present in the process or in the final product. The powerful HF-furnace with ZoneProtect and its wide detection range makes the G4 ICARUS Series 2 an excellent tool for the fast analysis of raw materials, intermediates and final products.

          Case Hardening

          Case Hardening

          Case hardening requires the control of the carbon potential during the carburization process. Direct furnace atmosphere analysis is used to determine the carbon potential by the ‘shim stock’ method, which utilizes heat treatment test foils that are placed inside the furnace. With its ease-of-use and long term stability the G4 ICARUS Series 2 is the perfect match for every parts manufacturer running a heat treatment/hardening shop.

          Limestone, Lime and Dolomite

          Limestone, Lime and Dolomite

          Limestone and Dolomite are sedimentary rocks with a tremendous variety of applications. Limestone is used as construction raw material, aggregate, fluxing agent, acid neutralizing agent. Dolomite is harder than limestone, making it a superior construction material. The G4 ICARUS Series 2 combines the ease-of-use and robustness to deliver fast and accurate carbon and sulfur results for the Quality- and Process-Control in these raw materials.
