WebOct 6, 2024 · The LLOQ is initially verified by spiking a clean control material (e.g., reagent water, method blanks, Ottawa sand, diatomaceous earth, etc.) at the LLOQ and processing through all preparation and determinative steps of the method. Laboratory-specific LLOQ recovery limits should be established when sufficient data points exist. WebSep 2, 2016 · The recovery range can go down to the LOQ (see Figure 2) of the method because most cleaning data should be near or below the LOQ of the analytical method. The recommended strategy for recovery levels is to spike 125% of the ARL, 100% of the ARL, and 50% of the ARL at a minimum, and to extend down to the LOQ of the test method as …
