Accurate determination of sulfur content in marine fuels is essential for compliance with international regulations and for ensuring fuel quality across diverse formulations, including those containing biofuel components. ISO 8754 specifies energy-dispersive X-ray fluorescence (ED-XRF) as the standard method for this elemental analysis, offering a non-destructive, efficient approach to quantifying sulfur concentrations. As marine fuels evolve to include higher proportions of fatty acid methyl esters (FAME), analytical methods must adapt to account for matrix effects introduced by varying oxygen content. The method described in ISO 8754, when applied correctly, enables precise sulfur quantification across a wide range of concentrations, supporting both regulatory compliance and operational reliability.
The SPECTRO XEPOS XRF analyzer engineered to meet the demands of this application with high reproducibility and minimal sample preparation. Its ability to automatically correct for matrix effects—such as those caused by oxygen from biofuel blends—ensures consistent accuracy without requiring prior knowledge of sample composition. By integrating advanced excitation and detection technologies, SPECTRO XEPOS delivers robust performance in sulfur analysis, making it a dependable tool for laboratories and fuel testing facilities engaged in marine fuel certification and quality assurance.
