In refinery and chemical plants, oil storage and blending terminals, bunkering for ocean-going vessels, and coal chemical quality inspection sites, the total sulfur content in oil products is a core indicator for environmental supervision and quality control. Sulfur dioxide (SO₂) emitted during the combustion of vehicle and marine fuels such as gasoline, diesel and heavy oil is a major cause of acid rain and atmospheric fine particulate pollution. In petrochemical fluid catalytic cracking units, excessive sulfides can directly poison and deactivate costly precious metal catalysts.
To strictly control sulfur content in oil products, stringent low-sulfur standards have been adopted at home and abroad (for example, China’s National VI vehicle fuel standard requires sulfur content below 10 ppm). Nevertheless, many small and medium-sized petrochemical enterprises and oil laboratories are plagued by cumbersome routine testing workflows. Conventional chemical titration or tube furnace combustion methods involve complicated preparation of chemical reagents, slow heating for high-temperature pyrolysis, and single-sample testing that often takes tens of minutes or even hours. Harmful gases generated in the process also tend to contaminate the laboratory environment.
To meet the urgent demand for fast, efficient and eco-friendly oil testing, Baoding Huazheng Electric Manufacturing Co., Ltd. has launched the HZ-1000XS X-ray Fluorescence Sulfur Analyzer, a compact, rapid and non-destructive energy dispersive X-ray fluorescence (EDXRF) sulfur testing instrument for the petroleum and petrochemical industry.
Non-destructive Testing in 60 Seconds, Greatly Shortened Analysis Cycle Adopting the physical fluorescence excitation principle, the HZ-1000XS avoids the tedious pre-treatment required by traditional chemical methods: Rapid and efficient measurement: Test duration can be freely set to 60 s, 120 s, 180 s (or adjustable from 30 s to 150 s). Routine testing automatically delivers analysis results in just 60 seconds; Simple and intuitive operation: No complicated chemical digestion or intense high-temperature combustion is needed. Simply draw 5 ml–6 ml of liquid sample (or 3 g of fine powder) with a disposable pipette into the sample cup, place it on the slide sample stage and start the test. The instrument will automatically feed the sample smoothly and perform precise measurement; Automatic statistics for single samples: Upon completion, the system automatically calculates and displays the mean value and standard deviation, multiplying testing efficiency compared with traditional chemical titration.
Wide Measurement Range, Fully Compliant with National Standards The instrument delivers outstanding overall analytical performance: Wide range from 0.0017% to 5%: It covers 0.0017% (17 ppm) to 5% with a detection limit of 10 ppm, suitable for ultra-low-sulfur refined light oil after desulfurization, as well as heavy crude oil, marine heavy fuel oil and residual oil; Full compliance with authoritative standards: Its repeatability and reproducibility fully satisfy the national standard GB/T 17040, petrochemical industry standard SH/T 0742, and the stricter ASTM D4294-03 standard issued by ASTM International.
Fast output and non-destructive, eco-friendly testing. With efficient and accurate optical physical analysis, the HZ-1000XS simplifies sulfur content control for oil products in a standardized and high-efficiency manner.
