MS:
| MS ID: | MS003036 |
| Analysis ID: | AN003264 |
| Instrument Name: | ABI Sciex 4000 QTrap |
| Instrument Type: | Other |
| MS Type: | ESI |
| MS Comments: | analyzed by a Waters UPLC with a 2.1×150 mm, 1.7 µm Acquity BEH column, ESI (+) and (-) switching and detection by multi-reaction monitoring on an Sciex 6500+ QTRAP mass spectrometer. We validated this method for linearity, limit of detection, limit of quantitation, inter- and intra-day reproducibility, and recovery for all targets, yielding better than 15% relative standard deviation and (spiked) recoveries of greater than 80%. |
