Before installing a different calibrant solution, be sure to flush the CDS tubing to remove any existing calibrant.
This procedure applies to both CDS bottles.
Required Materials
• Bottle of wash solution (1:1 water:acetonitrile)
• Waste container
1. Remove the calibrant bottle.
2. Put both ends of the calibrant tubing into a waste container, taking care not to submerge the tubing in liquid.
The container must hold at least 20 mL of additional solution that might come out of the instrument.
3. In the SCIEX OS, follow these steps to put the CDS into Wash mode:
a. On the status panel, click the
Direct CDS Control
icon.
The Device Control dialog opens.
Figure 3-7 Device Control (CDS)
b. Select
Wash Mode
.
This allows the pump to be controlled through the bottle sensor, which is located behind the bottle position.
4. Start the pump by pressing and holding the bottle sensor switch for 1 minute.
The CDS draws in air and discharges liquid. To stop the pump, stop pressing the switch.
5. Discard the waste.
6. Put the intake (left) tube into the bottle of wash solution.
7. Put the return (right) tube into the waste bottle.
