Total Sulfur, Nitrogen, and Chlorine Analyzer

Simultaneous Multi-Element Measurement: The HELIOS SN&CL Analyzer enables fast, fully automated, and simultaneous detection of ultra-low levels of sulfur, nitrogen, and chlorine in petroleum products—delivering comprehensive and efficient support for your analytical workflows.

Independent Combustion Tube Design: Equipped with two separate combustion tubes—one dedicated to sulfur and nitrogen, the other to chlorine—this design minimizes sample cross-contamination and significantly reduces downtime and reagent consumption during system flushing and maintenance, thereby enhancing overall analytical efficiency.

Utilizing UV fluorescence for sulfur, chemiluminescence for nitrogen, and coulometry for chlorine, the system automatically selects and executes the optimal analysis method without requiring manual adjustments based on sample concentration. This ensures high precision and reliability across a wide measurement range.

Automated Rinsing and Drying Function: The system features fully automated rinsing and drying, eliminating the need for sulfuric acid absorbers. This not only enhances operator safety by avoiding direct contact with corrosive liquids but also streamlines routine operation for greater convenience.

Intelligent Service Support: The system is equipped with built-in diagnostic functions that detect early signs of malfunction, enable preventive maintenance, identify required service actions, and display alerts—ensuring stable and uninterrupted instrument performance.
