Analysis is performed with UPLC peak separation followed by tandem MS/MS peak detection and mass spectral confirmation against an in-house fragment reference library. Chromatographic and spectral data are processed by quantitatively comparing the analytical peak areas against calibration curves prepared from certified reference standards. Pass/Fail limits have been established by the Massachusetts Department of Public Health but can vary from state to state.
