Assessment of (a) sensitivity and (b) workflow repeatability from the high-throughput metabolomics study by employing biological feature count and the intensity of putatively annotated features of the internal standards across 3 nESI-DIMS assays. Sensitivity and repeatability in intrastudy QC samples were determined on the whole dataset (ca. 1620 samples), whilst repeatability in biological samples employed a subset dataset comprising of control (unexposed) samples at 24 h (bottom right bar chart).
