21、y is a fast and reliable method for the quantitative analysis of the total content of certain elements within different matrices. The quality of the results obtained depends very closely on the type of instrument used, e.g. bench top or high performance, energy dispersive or wavelength dispersive in
22、struments. When selecting a specific instrument several factors have to be considered, such as the matrices to be analyzed, elements to be determined, detection limits required and the measuring time. The quality of the results depends on the element to be determined and on the surrounding matrix. D
23、ue to the wide range of matrix compositions and the lack of suitable reference materials in the case of inhomogeneous matrices like waste, it is generally difficult to set up a calibration with matrix-matched reference materials. Therefore this standard describes two different procedures: a quantita
24、tive analytical procedure for homogeneous solid waste, soil and soil-like material in the normative part. The calibration is based on matrix-matched standards; an XRF screening method for solid and liquid material as waste, sludge and soil in the informative Annex A which provides a total element ch
25、aracterisation at a semi-quantitative level. The calibration is based on matrix-independent calibration curves, previously set up by the manufacturer. EN 15309:2007 (E) 5 1 Scope This European Standard specifies the procedure for a quantitative determination of major and trace element concentrations
26、 in homogeneous solid waste, soil and soil-like material by energy dispersive X-ray fluorescence (EDXRF) spectrometry or wavelength dispersive X-ray fluorescence (WDXRF) spectrometry using a calibration with matrix-matched standards. This European Standard is applicable for the following elements: N
27、a, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Ag, Cd, Sn, Sb, Te, I, Cs, Ba, Ta, W, Hg, Tl, Pb, Bi, Th and U. Concentration levels between approximately 0,000 1 % and 100 % can be determined depending on the element and the instrument used. 2 N

40、s irrespective of the parameter to be determined. Waste and sludge samples may contain hazardous e.g. toxic, reactive, flammable, infectious substances, which could potentially undergo biological and/or chemical reaction. Consequently it is recommended that these samples should be handled with speci
41、al care. The gases that may be produced by microbiological or chemical activity are potentially flammable and will pressurise sealed bottles. Bursting bottles are likely to result in hazardous shrapnel, dust and/or aerosol. National regulations should be followed with respect to all hazards associat
42、ed with this method. The X-ray fluorescence spectrometer shall comply with European and national regulations relevant to radiation protection. The person responsible for managing or supervising the operation of X-ray equipment shall provide evidence of his knowledge of radiation protection according
43、 to national regulations. 5 Principle After a suitable preparation, if necessary, the sample is introduced into a XRF-spectrometer and excited by primary X-rays. The intensities of the secondary fluorescent energy lines specific for each element are measured and the elemental composition of the samp
44、le is determined by reference to previously established calibration graphs or equations and applying corrections for inter-element effects. The calibration equations and inter-element corrections are established using pure reagents and/or series of internal or reference materials providing they meet
45、 all the requirements of the relevant preparation technique. 6 Apparatus 6.1 X-ray fluorescence spectrometer The X-ray fluorescence spectrometer shall be able to analyse the elements according to the scope of this European Standard. The following types of X-ray fluorescence spectrometers are applica
46、ble: energy dispersive X-ray fluorescence (EDXRF) spectrometer that achieves the dispersion of the emitted X-ray fluorescence radiation by an energy dispersive detector; wavelength dispersive X-ray fluorescence (WDXRF) spectrometer that achieves the dispersion of the emitted X-ray fluorescence radia
47、tion by diffraction by a crystal or a synthetic multilayer. The spectrometer consists of a number of components: primary X-ray source, an X-ray tube with a high voltage generator; a sample holder; detector unit including electronic equipment; source modifiers to modify the shape or intensity of the
48、source spectrum or the beam shape (like source filters, secondary targets, polarising targets, collimators, focussing optics etc.). EN 15309:2007 (E) 8 The detector unit is different for WDXRF and for EDXRF spectrometers. WDXRF spectrometers take advantage of the dispersion of the emitted radiation
49、by scattering by a crystal or a synthetic multilayer. The detector does not need to be capable of energy discrimination. EDXRF spectrometers use an energy dispersive detector. Pulses of current from the detector, which are a measure of the energy of the incoming X-rays, are segregated into channels according to energy using a Multi-Channel Analyser (MCA). NOTE 1 The use of a high-energy X-ray tube increases the potential for losses of volatile analytes from samples by heating in the spectrometer during analysis. NOTE 2 Th
