Connect the inlet tubing
Connect the inlet tubing of the flow cell to the manifold for the QuikChem amperometric cyanide
method. Refer to
Figure 9 .
Figure 9 Plumb the inlet tubing
1 Manifold 3 Inlet tubing for the flow cell
2 Tubing to heater 4 Inlet fitting and tubing for the flow cell (factory
installed)
Remove bubbles from the system
Bubbles in the system cause an unwanted, regular pattern of baseline oscillation with a period that is
the same as the pump rollers.
1. Remove the reference electrode from the flow cell. Turn the reference electrode holder to remove
the reference electrode from the flow cell.
2. Supply deionized water to the flow cell as follows:
a. Connect a tube from the pump to the heater. Refer to item 2 in Figure 9 on page 19.
Refer to the QuikChem 8500 Series 2 Installation documentation for pump tubing installation.
b. Put the other end of the tube in a container of deionized water.
c. Set the pump to a low flow rate (e.g., 0.5 mL/min). For pump operation, refer to the QuikChem
8500 Series 2 Operations documentation.
The reference electrode hole starts to fill.
3. Let the deionized water fill the reference electrode hole until no more bubbles are seen in the
hole.
