BS EN 15837:2009 pdf free.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).
BS EN 15837 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 all of the safety problems associated with its use, but It is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
NOTE For the purposes of this document, the terms % (m4rn) and “% (VA’) are used to represent respectively the mass fraction (w) and volume fraction (i’).
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies, For undated references, the latest edition of the referenced document (including any amendments) applies.

A portion of a sample is directly injected into the spray-chamber of an inductively coupled plasma emission spectrometer. The element content is determined by comparing the emission of the element In the test portion with the emission of the calibration solutions at the same wavelength.
The calibration solutions are prepared from suitable compounds dissolved in ethanol.
