Ethanol as a blending component for petrol. Determination of phosphorus, copper and sulfur content. Direct method by inductively coupled plasma optical emission spectrometry (ICP OES) Ingestion-build-117251 symbols for transformer-operated meters1 Scope This European Standard specifies an inductively coupled plasma optical emission spectrometry (ICP OES) method for the direct determination of elements content in ethanol, namely phosphorus in the range (0,13 to 1,90) mg kg, copper in the range (0,050 to 0,300) mg kg, and sulfur in the range (2,0 to 15,0) mg kg. WARNING The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to
