The induction furnace of CS-900 series high-frequency

infrared carbon and sulfur analyzer with the function of

automatic reverse purging dust removal. When it used with a

dust extraction valve, it automatically removes a large amount

of dust from combust, to make sure the accurate and repeatable

analysis results, reducing manual cleaning time and increasing

efficiency. High working efficiency, the dust removal power

comes from the combustion exhaust gas, which truly realizes

energy saving and environmental protection.

Carbon and sulfur are one of the most widely distributed elements in nature. In the earth's crust,

carbon and sulfur usually exist in the form of compound (such as carbonate, sulfate) and element (such as

coal, sulfur). In the metal smelting process, no matter what smelting technology and craft is adopted,

carbon and sulfur will inevitably enter the metal material and form a variety of compounds, which will

have a certain impact on the properties of the metal. Therefore, in the entire smelting industry chain and

downstream industry chain, the analysis of carbon and sulfur elements is necessary.

The high frequency infrared carbon and sulfur analyzer is a fast carbon and sulfur analyzer, which

analyzer is a advanced carbon and sulfur analyzer at present, and it is widely used in fields of metallurgy,

machinery, scientific research, verification industries and etc.

Based on the principle of high-frequency induction combustion, the carbon and sulfur elements

contained in the sample are converted into CO2 and SO2. CO2 and SO2 have strong absorption bands at

4.26 μm and 7.4 μm respectively. By measuring the light intensity change after gas absorption, and

analyze the percentage of CO2 and SO2 gas concentration, indirectly determine the percentage of carbon

and sulfur in the measured sample. After circuit processing and analog-to-digital conversion, enter the

computer for data processing, and finally print out the analysis results by a printer.

The CS-902T high-frequency infrared carbon & sulfur analyzer is a cutting-edge instrument designed for precise and efficient analysis of carbon and sulfur content in various samples. This advanced technology utilizes a high-frequency induction furnace, which offers several advantages over traditional methods.

One of the key features of the CS-902T is its ability to handle a wide range of sample types, including those that are difficult to burn such as stainless steel, high-chromium steel, superalloys, master alloys, pure metals, ores, slag, sinter, graphite, and nonmetal oxide. This versatility makes it an ideal choice for laboratories involved in materials testing and quality control across different industries.

The high-frequency induction furnace used in the CS-902T operates at 18MHz, allowing for rapid heating and melting of samples. It can fully melt 1g of samples within 3 to 5 seconds, significantly reducing analysis time compared to traditional tube furnaces. The furnace's design also eliminates the need for long-term high-temperature radiation exposure, enhancing safety and durability.

Another critical aspect of the CS-902T is the selection of flux, which plays a crucial role in lowering the melting point of samples and producing exothermic oxidation effects during combustion. This not only facilitates sample burning but also improves the combustion temperature, ensuring accurate and consistent results. Common fluxes include tungsten particles and their alloys, industrial pure iron, and molybdenum trioxide, with the option to add tin capsules for enhanced performance.

The purification of O2 is also essential for accurate carbon and sulfur analysis. The CS-902T addresses this need by incorporating efficient color-changing desiccants and anhydrous magnesium perchlorate to remove moisture, and alkali asbestos to absorb carbon dioxide impurities. For ultra-low carbon and sulfur analysis, an ultra-pure oxygen purifier is recommended to further ensure the purity of the O2 supply.

At the heart of the CS-902T is its infrared detection system, which is based on the selective infrared absorption of CO2 and SO2. This system consists of an infrared light source, modulator, filter, measuring cell, detector, and related circuits. By leveraging the Lambert Beer's law, the infrared absorption of CO2 and SO2 provides a robust foundation for accurate analysis. The maximum absorption wavelengths for CO2 and SO2 are 4.26μm and 7.35μm, respectively, allowing for highly specific and sensitive detection.

In summary, the CS-902T high-frequency infrared carbon & sulfur analyzer offers unparalleled accuracy, efficiency, and versatility for carbon and sulfur analysis. Its state-of-the-art technology, combined with a user-friendly interface and robust construction, makes it an indispensable tool for any laboratory committed to excellence in materials testing and quality control.
