This European Standard shall be given the status of a national standard, eith

19、er by publication of an identical text or by endorsement, at the latest by April 2017, and conflicting national standards shall be withdrawn at the latest by April 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or C

20、ENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes CEN/TS 16170:2012. The preparation of the previous edition of this analytical method by CEN is based on a mandate by the European Commission (Mandate M/330), which assigned the development of

33、aqua regia soluble fractions of elements EN ISO 3696, Water for analytical laboratory use Specification and test methods (ISO 3696) 3 Principle Digests of sludge, treated biowaste or soil with nitric acid or aqua regia (see EN 16173 and EN 16174) are analysed by inductively coupled plasma optical em

34、ission spectrometry (ICP-OES) using sequential or simultaneous optical systems and axial or radial viewing of the plasma. The instrument measures characteristic emission spectra by optical spectrometry. Analyte species originating in the digest solution are nebulised and the resulting aerosol is tra

35、nsported to the plasma torch. Element-specific emission spectra are produced by a radio-frequency inductively coupled plasma. The spectra are dispersed by a grating spectrometer, and the intensities of the emission lines are monitored by photosensitive devices. NOTE For the determination of tin only

36、 aqua regia extraction applies (EN 16174). 4 Interferences Background correction is required for trace element determination. Background correction is not required in cases of line broadening where a background correction measurement would actually degrade the analytical result. Additional interfere

37、nces and matrix effects shall be recognised and appropriate corrections made. Tests for their presence are described below. DIN EN 16170:2017-01 EN 16170:2016 (E) 6 Spectral interferences are caused by background emission from continuous or recombination phenomena, stray light which causes backgroun

38、d increase or overlap of a spectral line from another element, or unresolved overlap of molecular band spectra. Background emission and stray light can usually be compensated for by subtracting the background emission determined by measurements adjacent to the analyte wavelength peak. Spectral scans

39、 of samples compared with single element solutions in the analyte regions may indicate when alternate wavelengths are desirable because of severe spectral interference. These scans will also show whether the most appropriate estimate of the background emission is provided by an interpolation from me

40、asurements on both sides of the wavelength peak or by measured emission on only one side. The locations selected for the measurement of background intensity will be determined by the complexity of the spectrum adjacent to the wavelength peak. The locations used for routine measurement shall be free

41、of off-line spectral interference (inter-element or molecular) or adequately corrected to reflect the same change in background intensity as occurs at the wavelength peak. Spectral overlaps may be avoided by using an alternate wavelength. Alternatively they can be corrected by multiple dimensional s

42、pectra fitting methods or by equations that correct for inter-element contributions. Instruments that use equations for inter-element correction require the interfering elements to be analysed at the same time as the element of interest. When operative and uncorrected, interferences will produce fal

43、se positive determinations and would be reported as analyte concentrations. The interferences are listed in Table B.1. If available, the user should apply multiple dimensional spectra fitting methods provided by the manufacturer, as a corrective action. In this case, the selection of background poin

44、ts for correction is not necessary, since all adjacent wavelengths are processed. Physical interferences are effects associated with the sample nebulisation and transport processes. Changes in viscosity and surface tension can cause significant inaccuracies, especially in samples containing high dis

45、solved solids or high acid concentrations. If physical interferences are present, they shall be reduced by diluting the sample, matching the acid concentration, matrix-matching, or a high solid nebuliser. They can be corrected for by using an internal standard. Chemical interferences include molecul

46、ar compound formation, ionisation effects, and solute vaporisation effects. Normally, these effects are not significant with the ICP technique, but if observed, can be minimised by careful selection of operating conditions (e. g. radio frequency (RF) power, observation position, gas flow rate and so

47、 forth), by buffering of the sample, by matrix matching, and by standard addition procedures. Chemical interferences are highly dependent on matrix type and the specific analyte element. Memory interferences result when analytes in a previous sample contribute to the signals measured in a new sample

48、. Memory effects can result from sample deposition in the uptake tubing or to the nebuliser and from the build-up of sample material in the plasma torch and spray chamber. The occurrence memory effects depend on the element and can be minimised by flushing the system with a rinse blank between sampl

49、es. The possibility of memory interferences should be recognised within an analytical run and suitable rinse times should be used to reduce them. The rinse times necessary for a particular element shall be estimated prior to analysis during method development. 5 Reagents For the determination of elements at trace and ultra-trace level, the reagents shall be of adequate purity. The concentration of the analyte or interfering substances in the reagents and t
