5. Verify that the column heater is set to the correct value.
Automatically Turning on the Suppressor and Eluent Generator
You can set up the ICS-2100 to turn on the suppressor, eluent generator, and
CR-TC automatically when the pump is turned on. To do this:
• For the suppressor, select the Automatically turn on with pump option from
the
SUPPRESSOR page.
• For the eluent generator and CR-TC, select the option from the ELUENT
GENERATOR
page.
NOTE The suppressor, eluent generator, and CR-TC are
always turned off automatically when the pump is
turned off.
3.8 Equilibrate the System and Verify Operational Status
NOTE You can monitor system functions (conductivity,
pressure, cell temperature, etc.) from the Chromeleon
Control panel or from the touch screen
HOME page.
1. Allow the system to equilibrate. During equilibration, the Chromeleon
Control panel displays the background conductivity (the conductivity of the
eluent before sample injection) and the system backpressure.
2. Monitor the background conductivity. Refer to the column manual for the
appropriate background conductivity for your application.
3. Offset the background and zero the reading by clicking the Autozero
button
on the Chromeleon Control panel (see Figure 3-4
).
4. Monitor the system pressure from the Control panel to make sure it is at the
expected pressure for the installed column (refer to the column manual for
details) and is stable.
• If the pressure is less than the expected amount, gas may be trapped in the
system. To release the gas, remove the pump fitting on the injection valve
port, labeled
P (2). Allow the air to escape and then reconnect the fitting.
• If the pressure fluctuates by more than about 0.13 MPa (20 psi), prime the
pump. See Section 4.3
for additional troubleshooting information.
