High-Precision Automatic Infrared Carbon Sulfur Analyzer for Steel & Iron Metal Analysis

A carbon sulfur analyzer is a specialized analytical instrument designed to determine the carbon(C) and sulfur (S) content in various solid materials. It is widely used in industries such as metallurgy, mining, cement, coal, ceramics, and quality control laboratories to ensure material quality and compliance with industry standards. The instrument delivers fast analysis - typically within tens of seconds-with high precision and a wide detection range from ppm level up to percentage level.

Carbon sulfur analyzers can be classified by analysis method and principle into several types, including infrared absorption method, gas volumetric method/iodometric method, non-aqueous titration method, and conductometric method. Among these, high-frequency induction combustion-infrared absorption method has become the absolute mainstream technology due to its high efficiency, accuracy, and high degree of automation.

The mainstream analysis method is high-frequency induction combustion-infrared absorption. The working principle involves three steps: sample combustion conversion, gas purification, and infrared detection.
