BS EN 16943:2017 describes a method for the determination of calcium, copper, iron, magnesium,
manganese, phosphorus, potassium, sodium, sulfur and zinc in different foodstuffs using optical
emission spectrometry with inductively coupled plasma (ICP-OES) after pressure digestion.
This method has been validated in an interlaboratory study according to ISO 5725 [1] on infant formula
soya based, cheese, chicken meat, wheat flour, apple juice, lobster and milk (see elements ranges
Table 1 and validation data in Annex B).
HorRat values greater than 2 have been observed for certain analyte/matrix combinations during the
validation study.
Table 1 - Validated element ranges
| Element | Range
mg/kg |
| Calcium | 70 to 7178 |
| Copper | 0,60 to 16,40 |
| Iron | 0,88 to 77 |
| Magnesium | 45 to 1 174 |
| Manganese | 0,44 to 5,12 |
| Phosphorus | 72 to 9 708 |
| Potassium | 605 to 14 312 |
| Sodium | 11 to 2 220 |
| Sulfur | 26 to 8 542 |
| Zinc | 0,16 to 43,5 |
At European or International level, vertical standards for the determination of specific minerals can
exist, e.g. for milk and milk products or for animal and vegetable fats and oils [2].
