BS EN 17053:2018 specifies a method for the determination of trace elements, heavy metals and
other elements in animal feed by inductively coupled plasma mass spectrometry (ICP-MS). The method
is used to determine As, Cd, Co, Cu, Fe, Hg, Mn, Mo, Pb, Se, Tl, U and Zn in the extraction solution after
pressurized digestion. For the determination of extractable lead in minerals and feeds containing
phyllosilicates (e.g. kaolinite clay) wet digestion with nitric acid should be used. The method described
is suitable for use in quadrupole instruments equipped either with or without additional technology to
reduce molecular ion interferences (e.g. collision or reaction technologies) as well as in high-resolution
sector-field systems.The method was fully statistically tested and evaluated in a collaborative trial comprising eight animal
feeding stuff samples for the elements As, Cd, Co, Cu, Fe, Hg, Mn, Mo, Pb, Se, Tl, U and Zn. For elements
with a HORRAT value higher than 2 (e.g. mercury, see Annex A) the method is more applicable as a
screening method and not for confirmatory purposes. High-resolution sector-field ICP-MS was not
tested in the validation ring trial.The limit of quantification for each element is dependent on the sample matrix as well as the
instrument. For the elements Co, Mn, Mo, Pb, Tl, U a limit of quantification of 0,10 mg/kg should
normally be obtained, for the elements Fe and Zn 5,0 mg/kg, while for Cd 0,03 mg/kg, Hg 0,04 mg/kg
and As 0,05 mg/kg should normally be quantifiable.Details on the successfully tested working range for each element are described in this standard.Cross References:EN ISO 6498EN ISO 3696EN ISO 6497 (ISO 6497:2002) ASISO 5725-5All current amendments available at time of purchase are included with the purchase of this document.
