This report describes the analytical precision of the S2 RANGER with XFlash® for low sulphur detection in automotive fuels and other petroleum products exceeding the actual international standards for EDXRF.
Sulphur is present in crude oil in concentrations up to about 5% by weight. It is therefore commonly found in derivative petroleum products from the % levels in lubricating oils down to trace levels in automotive fuels.
Sulphur concentrations in petrochemical products, like automotive fuels and lubricants, are of primary concern in the hydrocarbon processing industry. Harmful effects of sulphur on engine parts or machines and hazardous air pollution caused by sulphur oxides are driving regulations that require the reduction and accurate reporting of sulphur content. It has therefore become essential that sulphur concentrations be closely monitored and controlled in all petrochemical products.
