Abstract: In view of problems of tedious and time-consuming operation,poor security and serious pollution existed in current sulfur analysis methods,an infrared sulfur analyzer with dual channels was designed.The working principle,structure,designs of hardware circuit and infrared analysis pool of the analyzer were introduced.The analyzer is based on spectrum infrared absorption theory and uses dual channels thin film pyroelectric detectors to detect sulfur content of coal,ore and other substances quickly and accurately.The analyzer has many advantages,such as simple operation,fast analysis and high sensitivity.
