SPECTROPHOTOMETER - SPECTROMETER - Carbon and Sulfur Analyzer

Carbon and Sulfur Analyzer

Carbon and Sulfur Analyzer which can be used to detect the content of carbon or sulfur in metals, alloys and organic materials.

Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer is a high-end combined infrared carbon and sulfur analyzer of world-leading technology. 

Due to the diversity of specimens of users and analytical methods, the instrument is equipped with two sets of sample pre-treatment units, i.e. high-frequency induction furnace and tubular resistance furnace. The resistance furnace and the high-frequency induction furnace share the same infrared detection system for the detection of content of output gases to be detected. It is easy to switch between the two furnaces.

Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer can be used for the detection of carbon and sulfur in a wide range of specimens, such as steel, cast iron, alloy, metal ore, ceramics, cement, lime, rubber, coal, coke, refractory, carbide, graphite, oil, catalyst, soil and other solid materials.

Depending on the requirements of specimen detection, the resistance furnace or an induction furnace will be chosen as the specimen’s treatment unit. After purification, the carrier gas (oxygen) is imported into the combustion furnace and the specimen in the high-temperature combustion furnace will be oxidized by the oxygen to CO2, CO and SO2. After de-dusting and dehydration, the generated oxidation products are first loaded into the sulfur detection cell by the oxygen for the determination of sulfur content. Then the oxygen together with gas mixture comes into the heated catalytic furnace, in which catalytic oxidation happens and turns CO into CO2 and SO2 into SO3. After sulfur removal, the gas mixture is channeled to high-carbon detection cell and low-carbon detection cell in sequence by the oxygen for the determination of carbon content. The residual gas is finally discharged out. The analytical results of carbon and sulfur content will be displayed on the analysis software of the computer in the form of % C and % S, and automatically stored for later retrieval. The analysis software may generate, upon need, analysis reports which can be printed via an external printer.

Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer which is able to detect the content of carbon and sulfur in various materials fast and accurately is easy to operate and convenient for maintenance.
