Figure 4

Overall recovery of all targeted analytes in pooled samples analyzed by UPLC-Orbitrap MS. Columns and error bars present the overall recovery and relative standard deviation (), respectively. Red color indicates the recovery of the analyte out of an acceptable range (from 80 to 120%). (−) denotes an analyte that is measured in the negative electrospray ionization mode.
