When rinsing the flow cell before a low level standard calibration, be sure to rinse off the

inside of the reservoir lid with deionized water to prevent build up of sodium contamination
along the lid.
To ensure the analyzer achieves stability and minimize interference during calibration, the

operator should minimize activity on system during calibration.

Rinsing the Flow Cell

WARNING: Be sure to follow the procedure for rinsing the flow cell.
1. Open the sample inlet valve, see
Position the valve with the pointed end facing up for open position.

2. Open the bypass/needle valve by turning it counterclockwise, see
Check for the appropriate sample flow.

Adjust the pressure regulator if required. See step 3.
