The CS3500 carbon and sulfur analyzer adopts high-frequency heating and infrared detection principles, combined with new combustion and full-range detection technologies. It is widely used in industries such as steel and iron metallurgy, powder metallurgy, new energy, new materials, magnetic materials, non-ferrous metals, geological minerals, third-party testing, and scientific research institutes. It can simultaneously and rapidly analyze carbon and sulfur in solid materials such as steel and its alloys, metal powders, battery materials, rare earth magnetic materials, ceramic materials, electronic materials, ores, and soils.

Features of the instrument: 

Infrared detection system 

·Channel configuration: Standard with three independent infrared absorption channels. According to customer requirements, a high-sulfur channel can be added, allowing for a configuration of four independent infrared absorption channels. 

·Detector: It adopts a solid-state infrared detector imported from Germany, which has high sensitivity and is automatically zero-adjusted by a computer. 

·Motor: Swiss imported synchronous motor is adopted, ensuring continuous operation without failure. 

·Light source: It adopts imported infrared light source from the United States, which is not prone to oxidation and has stable optical performance. 

Constant temperature: The gas chamber is equipped with constant temperature control to ensure a stable temperature of the analysis gas and guarantee measurement accuracy. 

2. High-frequency combustion furnace system 

The high-frequency combustion furnace has a power of 2.7 KVA, is highly efficient, and ensures thorough combustion of samples. 

The anti-interference design featuring power supply isolation and decoupling through capacitors across the board ensures stable high-frequency power. 

It adopts a three-layer radiation shielding design, effectively shielding high-frequency radiation and ensuring the safety of the environment and laboratory personnel. 

It adopts a dedicated metal dust filtering device, which can be disassembled, washed and cleaned without any tools, and the operation is simple and quick. 

During each analysis process, the combustion chamber is automatically cleaned twice, and the system automatically vacuums and back-blow the air path to prevent air interference. 

By adopting the ceramic protective sleeve technology, the combustion chamber cleaning brush is protected, reducing the instrument's wear and tear. 

The dual gas-path combustion design features two gas inlet paths for the carrier gas, which not only prevents the splashing of lighter samples but also ensures their complete combustion. 

The dual airway cooling design cools both air and power gas simultaneously, ensuring stable operation of the instrument and reducing its wear and tear. 

3. Pneumatic System 

The micro-pressure difference flow control and high-precision electronic flow control technology for the analysis gas flow are adopted to ensure the absolute stability of the flow. 

The advanced PID control model can stabilize the airflow in a short time, and analysis can start 5 minutes after the gas is turned on. 

After the instrument is on standby, the system automatically enters an energy-saving state. 

The pneumatic circuit adopts a valve island integrated design, featuring a simple and stable process with no dead volume. 

4. Catalytic Conversion System 

Before the analysis gas enters the carbon channel, it passes through a copper oxide furnace for catalysis, converting the small amount of CO in the analysis gas into CO2, ensuring that all CO and CO2 produced during the sample combustion process can be detected completely. 

The analyzed SO2 is converted into SO3 and then absorbed by the SO3 trap to ensure no pollution is emitted. Users can choose to equip the copper oxide furnace device according to the sample testing requirements. 

5. Humanized analysis of the environment 

Chinese operation software for Windows 10/11 systems, convenient for users to operate, with free updates. 

Flexible quality input modes - automatic reading, manual reading, manual input, and automatic crucible tare. 

·Automatic range switching - automatic switching between high and low ranges for carbon and sulfur. 

Automatic removal of flux blanking 

·Reasonable parameter settings: 1. Flexibly adjust the analysis parameters according to specific samples. 2. Different calibration methods and parameters can be established and stored for different types of samples, and the number of analysis methods is not limited. 

·Powerful data management
1. Database storage, flexible query, and statistics 

2. Flexibly set the print columns according to user needs. 

3. Export current data on the analysis interface to EXCEL 

4. Data transmission function, seamlessly integrated with LIMS via network 

Rich information display - release curve comparison and saving, data result statistical processing, quick data query, maintenance reminder, and monitoring of important instrument parameters. 

Electromagnetic valve inspection - Can display and independently operate the actions of each electromagnetic valve. 

2. Signal acquisition check - It can monitor each acquisition signal of the system. 

3. High-frequency status check - High-frequency preheating monitoring 

4. Baseline Check - The system can monitor the baseline changes of each channel in real time. 

5. Automatic zero adjustment check - The baseline can be automatically adjusted to zero through software control.
