The method validation data for rye matrix are summarised in Table 2 as an example. Low LODs and LOQs were obtained for the different ergot alkaloids and matrices investigated. The reported LODs are in the range 0.04–0.29 μg/kg, whereas the LOQs are in the range 0.15–0.96 μg/kg. Since estimating the sensitivity of the method through LOD and LOQ lacks sufficient statistical significance, the concept of CCα and CCβ was introduced in Commission Decision 2002/657/EC.
