Are LOD and LOQ Reliable Parameters for Sensitivity Evaluation of Spectroscopic Methods? [PDF]

open access: yesJournal of AOAC INTERNATIONAL, 2018
Abstract The limit of detection (LOD) and the limit of quantification (LOQ) are common parameters to assess the sensitivity of analytical methods. In this study, the LOD and LOQ of previously reported terbium sensitized analysis methods were calculated by different methods, and the results were compared with sensitivity parameters [lower
