5.1.3 Calibrating the Conductivity Cell
When to Calibrate
•
After every 6 months of use
NOTE Do not use this procedure to calibrate a new cell. If you
are replacing a cell, see the instructions in Section 5.10
to install the new cell and calibrate it.
1. Open the ICS-2100 Wellness Panel in Chromeleon (see
Section 5.1.1 ), or open the touch screen ELECTRIC CONDUCTIVITY
CALIBRATION page (see Figure 5-3 ).
Items Needed Description
1.0 mM KCl solution Prepare by dissolving 0.07456 g of reagent-
grade KCl in 1 liter of 18-megohm DI
water.
Backpressure tubing to provide
at least 7 MPa (1000 psi) Use 0.076-mm (0.003-in) ID yellow PEEK
tubing (P/N 049715).
