A triple-quadrupole linear ion trap (QqLIT), which is the most widely used hybrid linear ion trap, is based on the ion path of a triple-quadrupole mass spectrometer with Q3 operated as either a conventional RF/DC quadrupole mass filter or a linear ion trap mass spectrometer. " A QqLIT combines the advantages of a QqQ and a QIT within the same platform without compromising the performance of either mass spectrometer. It retains classical QqQ functions such as MRM, product ion scan, precursor ion scan, and constant neutral loss scan for quantitative and qualitative analysis, and possesses MS" ion accumulation... [Pg.209]

Structure of the transformation product PTP-207B. As the weakest bond in this molecule was thought to be the nitrogen-carbon bond of the carbamate, the formation of m/z 134 was favored over other fragmentation routes. This resulted in a rather simple fragmentation pattern of PTP-207B in the positive ion mode. The other two transformation products were also identified with the comparison of MS spectral data (data not shown). As to the analytical approach employed, the use of LC-QqLIT-MS and UPLC-QqToF-MS proved to be a powerful combination for elucidating the imknown structures of the phototransformation products [18]. [Pg.67]
