Detection of the Carbon and Sulfur Content in Cast Iron by Carbon and Sulfur Analyzer (CAT#: STEM-EA-0011-ZJF)

Introduction

Carbon is the main alloying element in cast iron at levels greater than 2%. Sulfur is typically a contaminant in cast iron, and will prevent the formation of graphite, thus making the cast iron harder. Most foundries maintain sulfur at levels less than 0.15%.<br />We provide the detection of carbon and sulfur in a wide range of materials, including but not limited to: steel, aluminum, copper, titanium, nonferrous metals, ferroalloys, cast iron, alloys, coal, ash, carbides, casting core sand, ore, cement, minerals, lime, refractory, battery materials, gypsum, limestone, oil, soil, silicon, sand, slag, inorganic matter, ceramics, magnetic materials, catalysts, biomass, plant materials, rubber, tobacco, etc. If you have any requirements or questions. Don't hesitate to contact us.

Principle

Carbon and sulfur present in the sample are oxidized to carbon dioxide (CO2) and sulfur dioxide (SO2), and swept by the oxygen carrier through a heated dust filter, a drying reagent, and then through two infrared cells, where sulfur is detected as SO2. The gas flow continues past a heated catalyst, where carbon monoxide (CO) is converted to CO2 and where SO2 is converted to sulfur trioxide (SO3), which is subsequently removed by a filter. Then the CO2 is measured in up to two element selective IR cells. Finally, the combustion gas is led to the exhaust and the software calculates the resulting carbon and sulfur concentrations. The induction furnace is suitable for analyzing inorganic samples like steel, cast iron and ceramics, and the resistance furnace is used for combustion of organic samples like coal, coke or soil. The carbon and sulfur analyzer is a high-tech product that integrates optical, electrical, computer, and analytical technology into one.

Applications

Chemistry, plastics, coal, power plant, construction materials, engineering, electronics, commercial inspection, automobile industry, aviation, environment, recycling, agriculture, food industry, geology, mining, glass, ceramics, medicine, pharmaceuticals, steel, metallurgy, new energy, nuclear industry, petrochemical industry, scientific research, etc.

Procedure

1. Preparation: Log the sample into the software and the weight is automatically transferred.
2. Weighing (and adding of accelerators): For induction furnace, weigh the sample in a ceramic crucible and add accelerators like tungsten. For resistance furnace, weigh the sample and apply it directly to a boat.
3. Analysis: Place the sample on the pedestal or in front of the furnace and the analysis is started and contolled by the software.
4. Data output: After the analysis finished, the measured carbon and sulfur concentrations are available for export as a report or via LIMS.
