Connect one end of the backpressure coil to port
P
(

) on the injection
valve; connect the other end to the
TO INJ VALVE IN - P/ELUENT OUT
line
or to the mixer outlet, if an EGC CO3 Mixer is installed.

Verifying Operational Status
After the system has equilibrated, verify the actual pump pressure and stability by
monitoring the pump pressure reading on the IC system panel on the Chromeleon
panel tabset (or the touch screen
HOME
page). Write down the short-term pressure
fluctuations; they should be less than 0.13 MPa (20 psi).
You can acquire the pressure readings as a separate signal and plot the readings on
the IC system panel.
1. Verify that the pump pressure signal is enabled in the Server Configuration
program:
a.
Right-click the IC system device in the timebase and click
Properties
.
b. Click the
Signals
tab.
