The developed method was validated according to the Commission decision 2002/657/EC. Method linearity, limits of detection (LODs) and limits of quantification (LOQs), decision limit (CCα), detection capability (CCβ), system and method repeatability, within-laboratory reproducibility and method trueness in terms of recovery were evaluated by spiking experiments using sample material that was tested free from ergot alkaloids. Eventually, samples with very low levels of one or more of the analytes were used.
