Carbon and sulfur analyzers are used to quantitatively determine the carbon and sulfur content in steel, iron, and other materials. They use the gas volumetric method to measure carbon and the iodine titration method to measure sulfur.
The instrument integrates a microcomputer and single-chip microcomputer automatic control circuit, combining a high-sensitivity air pressure sensor with cold light source photoelectric conversion technology for automated testing. Test results are displayed digitally and can be printed. Equipped with patented electrodeless sulfur titration and dosing control technology and isolated touch-sensitive buttons, it can be used with an electronic balance to economically and efficiently perform variable-quantity sample weighing. The gas volumetric method determines carbon content through liquid collection, while the iodine titration method determines sulfur content through a titration reaction. Common maintenance requirements include cleaning arc furnace dust, checking pipe seals, and replacing desiccant.
Instrument Application: The carbon and sulfur analyzer can measure the content of carbon, sulfur, manganese, phosphorus, silicon, nickel, chromium, molybdenum, copper, titanium, zinc, vanadium, magnesium, and rare earth elements in cast iron, ductile iron, pig iron, stainless steel, plain carbon steel, alloy steel, alloy cast iron, various ores, and non-ferrous metals. The instruments offer a wide measurement range and high accuracy, offering a comprehensive range of high-, medium-, and low-end models, and are also able to accommodate custom orders. These products are widely used in steel, metallurgy, casting, mining, construction, machinery, electronics, environmental protection, health, chemical, electric power, and technical supervision departments, as well as in universities and colleges, and are highly sought after by users.

Main Features
Main Features of the Carbon-Sulfur Analyzer
Gas volumetric differential pressure carbon determination uses a highly sensitive pressure sensor to detect the results, and a single-chip microcontroller automatically processes the data, automating carbon readings.
Sulfur determination utilizes automatic iodine titration, eliminating human error and enabling direct digital reading of analysis results.
An electronic balance allows for online variable-volume sample weighing, with the microcontroller automatically reading the weight or manually entering the weight, improving analysis speed.
Patented electrodeless control technology for sulfur titration reduces malfunctions.
Isolated touch buttons eliminate interference and reduce malfunctions, offering convenient operation and a novel design. Structure and Principle
The Carbon and Sulfur Analyzer is a world-leading, high-tech carbon and sulfur analyzer launched in the new century. It features automatic switching between high carbon and low carbon, high sulfur and low sulfur, switching between resistance furnace and high-frequency furnace, high sensitivity, stable performance, accurate and reliable analysis results, a wide measurement range, and a wide range of applications. It can rapidly analyze carbon and sulfur content in solid and fluid materials such as steel, cast iron, copper, alloys, ores, cement, ceramics, carbon compounds, minerals, coal, coke, petroleum, ash, catalysts, lime, gypsum, soil, rubber, leaves, soot, garbage, sand, and glass.
Operating Principle: Purified carrier gas (oxygen) is introduced into a combustion furnace (either a resistance furnace or a high-frequency furnace). The sample is oxidized by oxygen at the high temperature of the furnace, converting the carbon and sulfur in the sample into CO2, CO, and SO2. The resulting oxides pass through dust and water removal and purification devices before being carried by oxygen into the sulfur detection cell for sulfur measurement. Afterward, a mixed gas containing CO2, CO, SO2, and O2 enters the heated catalyst furnace, where it undergoes catalytic conversion from CO to CO2 and SO2 to SO3. This mixed gas then enters the desulfurization reagent tube and is introduced into a carbon detection cell for carbon measurement. The residual gas is discharged from the analyzer to the outside. Simultaneously, the carbon and sulfur analysis results are displayed on the main unit's LCD screen and on a connected computer monitor as %C and %S, and are stored on the computer for easy access and printing to a connected printer.
The CS-2000 Carbon and Sulfur Analyzer can be operated on a computer with Windows-based software. During analysis, the instrument displays real-time operating status to ensure simple and reliable analysis. The combustion release curve of the sample is also displayed on the computer screen. The software features automatic calibration and diagnostics. The carbon and sulfur analyzer can be connected to a laboratory information management system (LIMS).
