Additional file 10 of Comparison between 5 extractions methods in either plasma or serum to determine the optimal extraction and matrix combination for human metabolomics

Additional file 10. Table S6. Unlabeled and labeled standard analytes used in the study. Mass weight expected and retention times are obtained from CD3.3 with several database onlines. Retention times are analyzed in either ESI mode of each column. ND stands for not detected. For details on the usage and fate of analytes in experiments see next Supplementary Tables and Figures. ESI : electrospray ionisation; RP: reverse phase.
