The center of the selected power mode icon changes from white to green. The System
LED on the front panel turns yellow. To keep the API source clean, the MS reduces the
auxiliary and sheath gas flows to their standby default settings (2 arbitrary). The MS turns
off the electron multiplier, conversion dynodes, 8 kV power to the API source, main RF
voltage, and ion optic RF voltages. For a more complete list, refer to
Chapter 11, “MS
Components On/Off Status.”
Shutting Down the MS System in an Emergency
1. To turn off the MS in an emergency, turn off the main power switch (1 in Figure 19 ) on
the power panel on the right-side of the MS. ( Figure 19 ).
This switch turns off all power to the MS, including the forepump, without harming
components within the instrument.
If you cannot safely reach the main power switch, unplug the power cord from the outlet.
2. To turn off the LC, autosampler, and data system computer in an emergency, use their
respective on/off switch or button.
