scope:

This European Standard specifies a method for the determination of the following elements in digests of aqua regia or nitric acid of sludge, treated biowaste and soil: Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), boron (B), cadmium (Cd), cesium (Cs), calcium (Ca), cerium (Ce), chromium (Cr), cobalt (Co), copper (Cu), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), gallium (Ga), germanium (Ge), gold (Au), hafnium (Hf), 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), rubidium (Rb), rhenium (Re), rhodium (Rh), ruthenium (Ru), samarium (Sm), scandium (Sc), selenium (Se), silicon (Si), silver (Ag), sodium (Na), strontium (Sr), sulphur (S), terbium (Tb), tellurium (Te), thorium (Th), thallium (Tl), thulium (Tm), tin (Sn), titanium (Ti), tungsten (W), uranium (U), vanadium (V), yttrium (Y), ytterbium(Yb), zinc (Zn), and zirconium (Zr). The working range depends on the matrix and the interferences encountered. The limit of detection is between 0,1 mg/kg dry weight and 2,0 mg/kg dry weight for most elements (see Annex B). The limit of detection will be higher in cases where the determination is likely to be interfered (see Clause 4) or in case of memory effects (see i.e. 8.2 of EN ISO 17294-1:2006).
