Figure 10. Front panel LEDs of the TSQ Quantum Ultra mass spectrometer
The Power LED illuminates green whenever power is supplied to the vacuum system and
electronic assemblies of the mass spectrometer.
The Vacuum LED illuminates yellow when the turbomolecular pump is nearly at speed
(80 percent of its operating speed of 750 MHz) and it is safe to turn on the ion gauge.
The Vacuum LED is off if the turbomolecular pump is not at speed. The Vacuum LED illuminates
green whenever the pressure in the analyzer chamber, as measured by the ion gauge, is at or below
the value required to enable high voltages to the mass analyzer (7 × 10
The Communication LED illuminates yellow when the mass spectrometer and the data system are
trying to establish a communication link. The Communication LED illuminates green when the
Ethernet communication link between the mass spectrometer and the data system has been made.
The System LED illuminates yellow whenever the mass spectrometer is in standby—that is, high
voltage is not supplied to the ion source, mass analyzer, or ion detection system, but the mass
spectrometer power is on. The System LED illuminates green whenever the high voltage is enabled
and the system is in the On state. High voltage is enabled if the analyzer chamber is below
7 × 10
The Scan LED flashes blue whenever the mass spectrometer is on and is scanning ions.
The syringe pump LED illuminates green whenever the syringe pump is pumping. The LED
illuminates yellow if the syringe pump is at the end of its travel.
Two additional LEDs and a push-button switch are located on the front panel above the
divert/inject valve. See
divert/inject valve button switches the valve between load and inject modes and the labels Load and
Inject apply.

When the divert/inject valve is set up for divert valve operation, the divert/inject valve button
switches the LC flow between the mass spectrometer and the waste container and the labels
