This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement,

20、 at the latest by April 2017, and conflicting national standards shall be withdrawn at the latest by April 2017.

DIN EN 16171:2017-01 EN 16171:2016 (E) 5 Introduction This European Standard is applicable and validated for several types of matrices as indicated in Table 1 (see Annex A for the results of vali

26、dation). Table 1 Matrices for which this European Standard is applicable and validated Matrix Materials used for validation Sludge Municipal sludge Biowaste Compost Soil Soil WARNING Persons using this European Standard should be familiar with usual laboratory practice. This European Standard does n

27、ot purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. IMPORTANT It is absolutely essential that tests conducted acc

28、ording to this European Standard be carried out by suitably trained staff. DIN EN 16171:2017-01 EN 16171:2016 (E) 6 1 Scope This European Standard specifies a method for the determination of the following elements in aqua regia or nitric acid digests of sludge, treated biowaste and soil: Aluminium (

29、Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), boron (B), cadmium (Cd), calcium (Ca), cerium (Ce), cesium (Cs), chromium (Cr), cobalt (Co), copper (Cu), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), gallium (Ga), germanium (Ge), gold (Au), hafnium (Hf),

30、holmium (Ho), indium (In), iridium (Ir), iron (Fe), lanthanum (La), lead (Pb), lithium (Li), lutetium (Lu), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), neodymium (Nd), nickel (Ni), palladium (Pd), phosphorus (P), platinum (Pt), potassium (K), praseodymium (Pr), rhenium (Re), rhodi

31、um (Rh), rubidium (Rb), ruthenium (Ru), samarium (Sm), scandium (Sc), selenium (Se), silicon (Si), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tellurium (Te), terbium (Tb), thallium (Tl), thorium (Th), thulium (Tm), tin (Sn), titanium (Ti), tungsten (W), uranium (U), vanadium (V), ytterbiu

32、m (Yb), yttrium (Y), zinc (Zn), and zirconium (Zr). The working range depends on the matrix and the interferences encountered. The method detection limit of the method is between 0,1 mg/kg dry matter and 2,0 mg/kg dry matter for most elements. The limit of detection will be higher in cases where the

33、 determination is likely to be interfered (see Clause 4) or in case of memory effects (see e.g. EN ISO 17294-1:2006, 8.3). The method has been validated for the elements given in Table A.1 (sludge), Table A.2 (compost) and Table A.3 (soil). The method is applicable for the other elements listed abov

34、e, provided the user has verified the applicability. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、art 1: General guidelines (ISO 17294-1:2004) 3 Principle Digests of sludge, treated biowaste or soil with nitric acid or aqua regia (see EN 16173 and EN 16174) are analysed by ICP-MS to get a multi-elemental determination of analytes. The method measures ions produced by a radio-frequency inductivel

38、y coupled plasma. Analyte species originating in the digest solution are nebulised and the resulting aerosol is transported by argon gas into the plasma. The ions produced by the high temperatures of the plasma are entrained in the plasma gas and introduced, by means of an interface, into a mass spe

39、ctrometer, sorted according to their mass-to-charge ratios and quantified with a detector (e.g. channel electron multiplier). DIN EN 16171:2017-01 EN 16171:2016 (E) 7 NOTE For the determination of tin only aqua regia extraction applies (EN 16174). 4 Interferences 4.1 General Interferences shall be a

40、ssessed and valid corrections applied. Interference correction shall include compensation for background ions contributed by the plasma gas, reagents, and constituents of the sample matrix. Detailed information on spectral and non-spectral interferences is given in EN ISO 17294-1:2006, Clause 6. 4.2

41、 Spectral interferences 4.2.1 Isobaric elemental interferences Isobaric elemental interferences are caused by isotopes of different elements of closely matched nominal mass-to-charge ratio and which cannot be separated due to an insufficient resolution of the mass spectrometer in use (e.g. 114Cd and

42、 114Sn). Element interferences from isobars may be corrected by taking into account the influence from the interfering element (see EN ISO 17294-1:2006). The isotopes used for correction shall be free of interference if possible. Correction options are often included in the software supplied with th

43、e instrument. Common isobaric interferences are given in Table B.1. 4.2.2 Isobaric molecular and doubly-charged ion interferences Isobaric molecular and doubly-charged ion interferences in ICP-MS are caused by ions consisting of more than one atom or charge, respectively. Examples include 40Ar35Cl+a

44、nd 40Ca35Cl+ion on the 75As signal or 98Mo16O+ions on the 114Cd+signal. Natural isotope abundances are available from the literature. The accuracy of correction equations is based upon the constancy of the observed isotopic ratios for the interfering species. Corrections that presume a constant frac

45、tion of a molecular ion relative to the “parent“ ion have not been found to be reliable, e.g. oxide levels can vary with operating conditions. If a correction for an oxide ion is based upon the ratio of parent-to-oxide ion intensities, this shall be determined by measuring the interference solution

46、just before the sequence is started. The validity of the correction coefficient should be checked at regular intervals within a sequence. Another possibility to remove isobaric molecular interferences is the use of an instrument with collision/reaction cell technology. The use of high resolution ICP

47、-MS allows the resolution of these interferences and additionally double-charged ion interferences. The response of the analyte of interest shall be corrected for the contribution of isobaric molecular and doubly charged interferences if their impact can be higher than three times the detection limi

48、t or higher than half the lowest concentration to be reported. More information about the use of correction factors is given in EN ISO 17294-1. 4.2.3 Non-spectral interferences Physical interferences are associated with sample nebulisation and transport processes as well as with ion-transmission eff

49、iciencies. Nebulisation and transport processes can be affected if a matrix component causes a change in surface tension or viscosity. Changes in matrix composition can cause DIN EN 16171:2017-01 EN 16171:2016 (E) 8 significant signal suppression or enhancement. Solids can be deposited on the nebuliser tip of a pneumatic nebuliser and on the cones. It is recommended to keep the level of total dissolved solids below 0,2 % (2 000 mg/l) to minimise deposition of
