QUALITY ASSURANCE OF SULPHUR DETERMINATION IN AUTOMATIVE FUELS AND PETROCHEMICAL PRODUCTS BY MICROCOULOMETRIC TITRATION METHOD

摘要

In this work results of analytical studies performed for determination of sulphur content in automotive fuels, aromatic hydrocarbons, gasoline fractions, hydrocarbon gases and polymeric products sulphur content determinations by microcoulometric titration method are generalised. Validated method procedures as response to imposed by the European Parliament strong requirements to automotive fuels and petrochemical products sulphur contents are proposed. High microcoulometric measurement quality and results traceability against certified reference materials (CRM-AR with sulphur content in crude oil of 0.0102%, SD=0.0009% and sulphur content in kerosene of 0.0011%, SD=0.0002%).
