Key Advantages

Advantage 1: High-efficiency, high-throughput automated testing capabilities

Utilizing infrared absorption spectroscopy, the system requires only about 3 minutes for single-sample analysis, significantly shortening the testing cycle. It accommodates 70 samples at a time and supports continuous sample loading; samples can be added, removed, or inserted during testing without interrupting the workflow. An MCPC control module enables standalone operation without host computer intervention, allowing for truly unattended processing and greatly enhancing batch testing efficiency.

Advantage 2: High-precision, highly stable testing performance

Equipped with an ultra-low-drift infrared cell and a three-barrel system that independently manages gas sealing, purging, and combustion, the instrument ensures a sulfur measurement resolution of 0.001% and consistent, accurate results. A temperature control precision of ±1°C further guarantees stability. The sample delivery system employs imported servo electric cylinders to minimize failure rates. Imported gas path components and an optimized gas circuit design ensure excellent airtightness and compliance with various national and international standards (such as ISO 19579), ensuring reliable and compliant test results.

Advantage 3: Safe, eco-friendly, and laboratory-friendly design

The instrument supports exhaust gas venting to prevent harmful gases generated during combustion from polluting the laboratory air. It also features real-time monitoring of laboratory temperature and humidity, enabling the timely detection of environmental anomalies and reducing experimental risks, thereby creating a safer and cleaner working environment for operators.

Advantage 4: Broad applicability and digital integration capabilities

The instrument is suitable for a wide range of samples, capable of determining the total sulfur content in various solid and liquid materials—including coal, coke, petroleum, combustion residues, cement, rubber, construction materials, and soil. The standard measurement range is 0.01%–40%, which can be extended based on user requirements. Additionally, it integrates with laboratory management systems to enable automatic balance data acquisition and the backup and uploading of test results, meeting the needs for digital and standardized laboratory management.
