Additional file 15 of Comparison between 5 extractions methods in either plasma or serum to determine the optimal extraction and matrix combination for human metabolomics

Additional file 15. Table S11. Summary of sensitivityfor labeled standard analytes across all extraction methods and LC-MS analyses. Sensitivity is given by the calibration curve slope, and the LOD and LOQ values are calculated as those corresponding to the signal-to-noise ratios of 3:1 and 10:1, respectively. The table displays a mean of LOD and LOQfor plasma vs. serum in each LC-MS conditions. Empty boxes stands not detected. LOD : limit of detection; LOQ : limit of quantitation; MeOH : methanol; MeOH:ACN : methanol combined with acetonitrile; ACN: acetonitrile; SPE : solid preparation extraction; ESI : electrospray ionisation; RP: reverse phase.
