AB Sciex QTRAP 5500 coupled with Shimadzu LC-20 HPLC

Acquired in 2010, QTRAP 5500 is a high-sensitivity, bench-top, hybrid triple-quadrupole, and linear-accelerator-trap mass spectrometer designed for LC-MS/MS analyses. Available ionization sources include both ESI and atmospheric pressure chemical ionization. The instrument can operate as both a triple-quadrupole and linear-ion-trap mass spectrometer simultaneously, allowing for both quantitative and qualitative analyses to be carried out in the same experiment.
