EN 15837:2009 (E) 4 1 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 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 “% (m/m)” and "% (V/V)" are used to represent respectively the mass fraction (w) and volume fraction (ϕ). 2 Normative references 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.

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. 4 Reagents Use only reagents of recognized analytical grade, unless otherwise specified. 4.1 Phosphorus standard solution, ready-made commercially available phosphorus aqueous standard solution, 1 000 mg/l. 4.2 Copper standard solution, ready-made commercially available copper aqueous standard solution, 1 000 mg/l. 4.3 Sulfur standard solution, which shall be either 4.3.1 or 4.3.2. 4.3.1 Sulfur standard solution, ready-made commercially available sulfur aqueous standard solution, 1 000 mg/l, or
