Ethanol as a blending component for petrol - Determination of sulfur content - Wavelength dispersive X-ray fluorescence spectrometric method

This technical specification outlines a standardized method for determining sulfur content in ethanol intended as a blending component for motor gasoline. The procedure relies on wavelength-dispersive X-ray fluorescence spectrometry to ensure high precision and accuracy in quantitative analysis. By employing this specific analytical approach, laboratories can effectively measure trace levels of sulfur within the fuel additive, which is critical for meeting environmental regulations regarding fuel quality and emissions control. The method is designed to be applied during the production and quality assurance stages of ethanol fuel processing. It provides a reliable framework for verifying compliance with maximum allowable sulfur limits to support the manufacturing of cleaner-burning transportation fuels. Adherence to this guideline ensures consistency in testing results across different facilities and supports the broader objective of reducing harmful pollutant emissions from vehicles operating on ethanol-gasoline blends.
