E.2.2.2 Connecting the diverter valve to the electricity source
Warning:
To avoid electric shock, observe these precautions:
• Inspect the power cords for damage and replace them if necessary.
• Power-off and unplug each module before performing any maintenance operation
on it.
• Connect each module to a common ground.
To connect to the electricity source:
Recommendation:
Use a line conditioner and uninterruptible power supply (UPS) for optimum
long-term input voltage.
1.
Connect the female end of the power cord to the receptacle on the rear panel of the
detector.
2.
Connect the male end of the power cord to a suitable wall outlet.
E.2.3 Configuring the diverter valve fluidics
The ACQUITY diverter valve can be configured to switch the sample flow direction between the
QDa and waste in divert mode, or configured in loop injection mode.
Warning:
To avoid electric shock, ensure that the ACQUITY Diverter Valve is
grounded before connecting the ESI probe. The diverter valve is grounded by fitting it to
the mounting bracket on the instrument and plugging in the power supply unit.
Notes:
• The descriptions and figures in this section show diverter valve configurations based on
common setups of the ACQUITY QDa Detector and the ACQUITY Diverter Valve. For details
about alternative LC tubing on system configurations that include in-line optical detectors, see
Diverter valve tubing considerations
• In the
QDa Method Events
tab, the ON command refers to position 1 and the OFF command
refers to position 2.
