Target Analysis of Serum-Extract using MS/MS Mode (MRM and subsequent
Product Ion Scan for different Compounds, including e.g. Morphine and Zopiclon).

Fig. 1: Upper panel: TIC; three panels (2nd to bottom) resulting in three +MS2 spectra at 20, 35 and 50 eV CE

 

Identification by Library Search (50 eV MS/MS spectrum)

Yielding good fit values (0.974 for fit, 0.974 for reverse fit, 0.973 for purity fit).

Applications:

 a) Compound Identification after Screening with LC-in-sourceCID-MS

 b) Multi Target-Screening Analysis (MRM mode) with subsequent MS/MS and identification by library search
