3. On the Wellness panel under External Conductivity Cell Calibration,
click Instructions for a summary of the procedure (described in detail in
this section).
4. Disconnect the pump output line from the injection valve.
5. Disconnect the line from the suppressor
and connect the pump output line directly to the cell inlet.
6. Verify that backpressure at the pump is at least 7 MPa (1000 psi) at
0.01 mL/min (for capillary) or 1.00 mL/min (for analytical).
7. Set the cell heater to 35 °C
LED stops blinking).
8. Begin pumping 1.0 mM KCl through the cell at 0.01 mL/min (for
capillary) or 1.0 mL/min (for analytical).
9. Wait until the total conductivity reading stabilizes (15 to 30 minutes).
10. On the Wellness panel, click Calibrate.
After calibration, the conductivity reading should be 147.00 ± 2
is not the case, repeat the calibration.
11. To record the new calibration value in the Audit Trail, click Log.
