To interrupt operation of the device for a short period (short-term shutdown), for example, overnight, observe these guidelines for the Vanquish system modules, as required by your system arrangement:
For your Vanquish detector, note the following:
Detector Type | Description |
|---|---|
Charged aerosol detector | Check that sufficient gas is available to continue gas flowing through the detector. This is to prevent any build-up of residue from solvents or analytes. Gas must be flowing when pump flow is delivered to the detector. |
UV/VIS detectors | The lamp(s) in the detector can remain turned on. Variable wavelength detector and VH-D10 diode array detector only: The shutter can be moved to a closed position for protection of the flow cell. |
Fluorescence detector | Turn off temperature control for the flow cell. |
Apply a flow of 0.05 mL/min and have the pump deliver an appropriate solvent.
Check the lower pressure limit for the pump and adapt the value if necessary. If the pressure falls below the lower limit, the pump stops the flow.
Set the injection valve in the autosampler to the Inject position.
Make sure that the temperature of the column does not exceed 40 °C.
When resuming operation, let the flow equilibrate and verify that the operating parameters for the other system modules are set as required before proceeding.
