X-Ray Fluorescence Determination of Sulphur in Oils by a Thin Film Method.
Abstract
A thin film dilution sample preparation technique for the determination of sulphur in petroleum products is described. An internal control standard compensates for variations in oil film thickness. The procedure utilises a mixture of sample and an alkyd resin to improve adhesion to a Mylar substrate and to reduce sample flow during irradiation. The method is quantitative and has good repeatability for sulphur contents up to 5%. Accuracy is comparable with that obtained by chemical methods. The detection limit for sulphur was estimated to be 0.03%.
