• Carbon and Sulfur Determination by Combustion Elemental Analysis Innovation with Integrity

Simultaneous carbon and sulfur analysis by combustion The elemental content of carbon and sulfur within a material has a great impact on its physical properties. In steels, the carbon content determines properties like hardness, ductility, brittleness and magnetism and determines the actual grade of low alloy steels. Due to their impact on the material properties, carbon (C) and sulfur (S) are monitored along the whole production process. 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,...

Principle The solid sample, placed in a ceramic crucible together with accelerator material, is heated directly using a sealed high-frequency (HF) induction furnace. The molten sample is combusted in a flow of pure oxygen. The pressurized oxygen flow in combination with Bruker's unique ZoneProtect™ ensures a complete, clean combustion without undesirable side effects. During combustion carbon and sulfur components in the sample are converted into CO2 and SO2. Traces of CO are oxidized downstream to CO2. These combustion gases are transported with the oxygen carrier gas for detection by advanced...

ZoneProtect™ -Clean, Fast & Efficient Combustion Bruker's unique ZoneProtect design ensures a long lasting combustion tube and virtually eliminates any maintenance on this vital part. ZoneProtect further shields the entire combustion zone against splatters and dust deposits and supports a complete combustion. Unlike conventional designs operating with a lance, blowing oxygen over the sample or using proprietary high crucibles with slow combustion, the innovative principle of ZoneProtect knows no compromises. The G4 ICARUS Series 2 with ZoneProtect™ combines speed and outstanding analytical performance...
