摘要
A mass spectra (MS) library using in-source collision induced dissociation (ESI-CID) as well as a tandem-mass spectra (MS-MS) library with product ion spectra of drugs has recently been developed with a triple-quadrupole ionspray mass spectrometer [1,2]. For the ESI-CID MS library, single-quadrupole mode and for the MS-MS library triple-quadrupole mode have been used. These mass spectra libraries were applied successfully for the general-unknown screening for drugs and metabolites in serum and urine with liquid-chromatography-mass spectrometry (LC-MS) using a PE/SCIEX API 365 with a turboionspray source. As examples, the identification of lorazepam and lorazepam-glucuronide in a serum extract and the identification of sildenafil and alkyloxidated sildenafil in urine are presented here.
