LCQ Advantage


The Finnigan LCQ Advantage is an ion trap mass spectrometer.  The instrument is capable of performing single stage LC/MS and two-stage LC/MS/MS experiments.  Sample solutions could be introduced to the mass spectrometer via a loop injection or directly infused by a syringe pump. The LCQ components are shown in Figure 1.  The instrument is equipped with an atmospheric Pressure

ionization (API) interface, LC pump, Syringe pump, PDA detector, and Surveyor auto-sampler. Ions are generated in the Electrospray or APCI ion sources.  The instrument can be operated in positive ion mode or negative ion mode.
