4. Flush and store the system with 50:50 water/acetonitrile (or methanol). Switch the injector
valve between load and inject a few times. Ensure that all tubing and filters are flushed so
no traces of salt are left that could precipitate and clog the system.
5. Remove the flow cell from the system by disconnecting the inlet and outlet capillary.
6. Open the cell, flush with water, and use some tissues to carefully dry the cell. Be careful
not to damage the spacer in a VT-03 or FlexCell (the SenCell does not have a spacer).
7. Close the cell and store dry. In the case of a salt bridge REF, cap it and store it separately
to prevent drying out. Alternatively, put the sb-REF in a 10-mL vial under a KCl solution
and close the vial with a cap.
8. Switch off the detector (and other LC equipment) via the main switch (switch to position
"0") on the rear panel.
Notice:
Avoid precipitation of high salt concentrations in organic solvent. Wash
out salts with water if necessary.
Note:
If the electrochemical detector will be idle for less than a week, provided the flow
cell is switched off, the detector can be left idle or powered-down, with the solvent flowing
at a low flow rate. When ready for the next analysis, you can switch on the detector with
the flow cell and fresh mobile phase and re-equilibrate.
