General Information
Overview
EN 14084:2003 (CEN) is a horizontal European standard that specifies a validated analytical method for the determination of trace elements - lead (Pb), cadmium (Cd), zinc (Zn), copper (Cu) and iron (Fe) - in foodstuffs. The method couples microwave closed‑vessel digestion (nitric acid + hydrogen peroxide) with atomic absorption spectrometry (AAS) (graphite furnace AAS for Pb/Cd and flame AAS for Zn/Cu/Fe). It was successfully validated in an interlaboratory trial with 16 laboratories. The standard excludes oils, fats and extremely fatty products.
Key Topics & Requirements
- Scope: Applicable to a wide range of food matrices (composite diets, cereals, fish, beef, milk, fungi); excludes specialised vertical standards and very fatty matrices.
- Sample preparation: Homogenisation and optional gentle drying (e.g., freeze‑drying). Typical test portion: 0.2–0.5 g dry matter (guidance given for wet samples).
- Microwave digestion: Closed vessels (~100 ml capacity) using concentrated nitric acid (≥65%) and 30% hydrogen peroxide; vessels must withstand ≥1.4 MPa. Typical reagent volumes: ~5 ml HNO3 + 2 ml H2O2 (manufacturer programmes determine power/time).
- AAS instrumentation:
- Graphite furnace AAS (GFAAS) with pyrolytically coated tubes and platforms for Pb and Cd; autosampler recommended.
- Flame AAS for Zn, Cu and often Fe (but Fe may require standard additions or matrix‑matched standards due to matrix interferences).
- Background correction and element‑specific lamps (hollow cathode) are required.
- Calibration and quantification: Use certified standard solutions (examples given at 1 000 mg/L) and prepare calibration or standard additions covering the linear range. The method generally recommends the method of standard additions unless matrix matching is validated as sufficient.
- Calculation: Result calculated from concentration in digested solution, reagent blank and sample mass per the formula provided in the standard.
- Performance: Repeatability and reproducibility limits are reported from the interlaboratory study; limits are matrix‑ and concentration‑dependent.
Applications & Users
- Food testing and quality control laboratories performing trace element analysis for regulatory compliance and consumer safety.
- Public health and food safety authorities monitoring heavy metal contamination in the food chain.
- Research laboratories studying dietary exposure, contamination sources or food processing impacts.
- Food manufacturers and certification bodies requiring validated methods for Pb, Cd, Zn, Cu, Fe measurement.
