Liquid petroleum products - Determination of organic oxygenate compounds and total organically bound oxygen content in unleaded petrol - Method by gas chromatography (O-FID)

This document establishes a standardized analytical procedure for determining the content of organic oxygenated compounds and total organic oxygenated compounds in leaded-free gasoline derived from liquid petroleum products. The methodology utilizes gas chromatography equipped with an oxygen flame ionization detection system, commonly abbreviated as GC with O-FID. This approach provides a reliable means to quantify oxygenate levels within fuel samples, ensuring compliance with specific quality parameters. The procedure outlines detailed requirements for instrument setup, calibration, sample preparation, and data analysis to ensure reproducibility and accuracy across different testing environments. It covers the identification of specific oxygenated species and the calculation of their total concentrations based on chromatographic peaks. By defining precise operational parameters, this specification facilitates consistent evaluation of fuel composition, supporting quality assurance efforts in the petroleum industry. The method is applicable to the analysis of finished gasoline products and serves as a technical reference for laboratories engaged in fuel testing activities.
