ASTM D4294 Petroleum XRF Sulfur Analyzer
ASTM D4294 Petroleum XRF Sulfur Analyzer
MT-XS300
The XRF Sulfur Analyzer is designed for rapid and accurate determination of total sulfur content in petroleum products, petrochemical samples, and related materials. The instrument is developed based on the energy dispersive X-ray fluorescence (EDXRF) principle, providing non-destructive and high-precision sulfur analysis.
Introduction
Sulfur content is a critical parameter in petroleum products due to its significant impact on environmental pollution, fuel quality, and industrial processes. During fuel combustion, sulfur compounds generate sulfur dioxide (SO₂), which contributes to air pollution, acid rain, and catalyst poisoning in petrochemical processes. Therefore, international regulations strictly limit sulfur content in fuels such as gasoline, diesel, and heavy oils.
This XRF Sulfur Analyzer complies with ASTM D4294, as well as GB/T 17040, GB/T 11140, and SH/T 0742, providing reliable sulfur content measurement for crude oil, refined products, and petrochemical materials.
The instrument features a compact mechatronic design, fast analysis speed, high accuracy, and excellent repeatability, making it an essential tool for modern petroleum laboratories.
Typical Applications
The ASTM D4294 Sulfur Analyzer is widely used for determining total sulfur content in various liquid and solid samples.
