Petroleum and Fuels

In the oil and petroleum industry, precise elemental analysis is essential for quality control, regulatory compliance, and process stability. Wavelength dispersive X-ray fluorescence (WDXRF) spectrometry provides fast, accurate, and non-destructive measurement of key elements such as sulfur, lead, nickel, and vanadium across crude oils, fuels, and lubricants. With superior sensitivity and repeatability, WDXRF supports reliable monitoring from production to final product certification.

WDXRF has been widely applied in the petroleum and fuel industries, demonstrating how precise elemental analysis supports quality assurance, process optimization, and environmental compliance.

Crude and heavy oils: Quantification of sulfur, nickel, and vanadium helps evaluate crude quality and monitor impurities that affect refining performance.
Refined fuels (gasoline, diesel, kerosene): Accurate sulfur and lead quantification ensures compliance with international environmental standards.
Lubricating oils: Multi-elemental analysis verifies additive composition and detects contamination that can affect engine performance.
Residual oils and recycled fuels: Elemental profiling of heavy fractions supports process optimization and quality assurance in secondary fuel applications.

The application notes below provide real measurement data from these representative cases, demonstrating the versatility of WDXRF for both research and routine quality assurance across the petroleum value chain.
