ASTM D5453 UV Fluorescence Sulfur Tester
ASTM D5453 UV Fluorescence Sulfur Tester
MT-US500
The UV Fluorescence Sulfur Tester is designed for the determination of total sulfur content in light hydrocarbons, motor fuels, and petroleum products using the ultraviolet fluorescence method. The instrument is developed in accordance with SH/T 0689 and fully complies with ASTM D5453.
Introduction
Sulfur content is a critical parameter for evaluating fuel quality and environmental impact. During combustion, sulfur compounds generate sulfur dioxide (SO₂), which contributes to air pollution and acid rain. With increasingly stringent fuel regulations such as Euro V standards, accurate determination of ultra-low sulfur content has become essential.
This UV Fluorescence Sulfur Tester adopts the ultraviolet fluorescence detection principle, providing high sensitivity, wide linear range, and excellent repeatability, making it especially suitable for low sulfur and ultra-low sulfur analysis.
The system integrates combustion furnace, UV detection module, gas flow control, and computer-based data processing, enabling fast and reliable sulfur analysis for a wide range of sample types.
It is widely used in petroleum, petrochemical, power generation, coal, environmental protection, and research laboratories.
