Methods of analysis: specific performance requirements
Parameter |
Criterion |
Applicability |
Foods specified in Regulation (EC) No 1881/2006 |
Selectivity |
Analytical methods shall demonstrate the ability to reliably and consistently separate the analytes of interest from other co-extracted and possibly interfering compounds that may be present. |
Within-laboratory reproducibility (intermediate precision)(RSDR) |
≤ 20 % |
Trueness |
-20 % to +20 % |
LOQ |
The LOQ for PFOS, PFOA, PFNA and PFHxS each ≤ the maximum level for the respective individual PFAS. Compliance with this requirement entails that no LOQ shall be derived for the concentration of the sum of PFOS, PFOA, PFNA and PFHxS, which is calculated by summing up only the concentrations of PFOS, PFOA, PFNA and PFHxS, which were quantified at or above their respective LOQ. |
