1 Scope
This document specifies a procedure for the determination of Ag, As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, Se, Tl,
U and Zn in foodstuffs by inductively coupled plasma mass spectrometry (ICP-MS) after pressure
digestion.
The following foodstuffs were analysed for the elements listed in Table 1 in an interlaboratory study:
Banana (deep-frozen), Cocoa powder, Wheat noodle powder, Currant nectar (deep-frozen), Milk powder,
Oyster (dried), Celery (dried), Dogfish liver (dried), Liver (deep-frozen), Kale (dried).

Table 1 lists the ranges analysed in the interlaboratory study, indicating for each element the lowest and
highest content found in the ten analysed food matrices (see Annex B, Table B.1 to Table B.14).
The lower limit of the procedure’s range varies depending on the food matrix and the food’s water content.
It is a laboratory-specific value and is specified by the laboratory for each element when calculating the limit
of quantification (see 9.2).

4 Principle
The sample is digested. For the digestion the pressure digestion process in EN 13805 shall be used, in the
case of foodstuffs with a low water content, after adding water. In the digestion solution, the elements
silver, arsenic, cadmium, cobalt, chromium, copper, manganese, molybdenum, nickel, lead, selenium,
thallium, uranium and zinc are quantified by ICP-MS. For this purpose, the digestion solution is nebulized
and the aerosol is transferred to an inductively coupled argon plasma where the elements are ionized.
The ions are transferred via a system of cones into a mass spectrometer, where they are separated
according to mass-to-charge ratio and detected by pulse and/or analogue detector.
The respective content of the elements mentioned in Clause 1 is understood as the total content
measured using this described procedure. It is expressed in mg/kg or mg/l, depending on the sample
type.
For other elements not specified within the scope, other documents can be considered, e.g. EN 15763. For
the determination of aluminium and tin in foodstuffs refer to EN 17264 and EN 15765.
5 Reagents
The chemicals, gases and water used shall be free enough from the elements to be determined to not
affect the results. Unless otherwise specified, “solutions” are understood to be aqueous solutions.
5.1 Nitric acid, mass fraction of min. ω = 65 %, density ρ ≈ 1,4 g/ml.
5.2 Stock solutions
A commercially available multi-element stock solution, for example with ρ = 10 mg/l, can be used for
silver, cadmium, cobalt, chromium, copper, manganese, molybdenum, nickel, lead, thallium, uranium and
for example with ρ = 100 mg/l for arsenic, selenium and zinc.
Alternatively, commercially available single-element stock solutions, for example with ρ = 1 000 mg/l,
can be used.
When using single-element stock solutions, attention shall be paid that they are suitable for ICP-MS, i.e.
are of sufficiently high purity, to generate no additional contamination with other elements to be
determined. If mixing the single-element stock solutions, attention shall also be paid to chemical
compatibility.
NOTE Depending on the manufacturer, stock solutions with 10 000 mg/l can also be used i
