when a vacuum fault is detected. In pump-down mode, the Ready light flashes for the duration of
the sequence.
Directly below the ion source is a set of integrated sample introduction features. An integrated
switching valve with associated Load and Inject buttons (marked A and B, respectively) can
be used as a manual injector during analyte optimization using FIA, or for diverting LC flow
when any precipitate or salts initially come off the LC column. Below that, an integrated syringe
pump is available for infusing standards when the system is calibrating the mass spectrometer
or optimizing for an analyte.
