The system supports rapid analysis and detection of sulfur content in gasoline, diesel, and other petroleum products. It is applicable to total sulfur determination across a broad concentration range—from low‑sulfur fuels to crude oil—and is well‑suited for use in refinery laboratories, pipeline terminals, marine applications, additive production facilities, inspection vehicles, and testing laboratories, among other settings.

The system is designed in compliance with GB/T 17040‑2019 "Determination of Sulfur Content in Petroleum and Petroleum Products – Energy Dispersive X‑ray Fluorescence Spectrometry". For sample sulfur content at or below 10 mg/kg, the relative standard deviation (RSD) is ≤ 10%; for sulfur content above 10 mg/kg, the RSD is ≤ 5%.

The instrument incorporates built‑in radiation shielding and a safety interlock system. During operation, the sample chamber remains closed, ensuring a fully enclosed measurement environment, and a user prompt is provided to confirm chamber closure. The design includes anti‑vibration and radiation protection features. A 7‑inch industrial‑grade color touchscreen facilitates intuitive user interaction.

Data transfer via USB and LIMS integration is straightforward and efficient. The system is equipped with 64 GB of storage, and supports printing, USB connectivity, Wi‑Fi, and Bluetooth.
