The LOD and LOQ are important parameters for an analytical
method used to estimate residues in foodstuffs, especially when
there is interest in monitoring residues that do not have established
MRL (Codex, 2009).
The LOD and LOQ were always below
0.05 lg kg1 and 0.16 lg kg1 respectively (Table 4). These results
indicate that the proposed method is sufficiently sensitive for trace
analysis of ML in butter.
