3.7 Set System Operating Conditions
NOTE This section is an overview of the steps needed to start
up the system and begin running samples. Actual
operating parameters (flow rate, cell heater
temperature, suppressor current, etc.) depend on the
application to be run. Refer to the column manual for
the required parameters for your application.
Set or verify system operating parameters from the Chromeleon Control panel.
Operating parameters can also be set automatically by loading a Chromeleon
sequence.
NOTE Clicking the System Startup button on the Chromeleon
Control panel starts the pump and suppressor. The flow
rate and suppressor current settings that were in effect
when the system was shut down are restored.
1. Verify that the pump is on and set to the correct flow rate.
2. Verify that the suppressor current is on and that the setting is correct.
3. Verify that the cell heater is set to the correct value.
4. Verify that the column heater is set to the correct value.
3.8 Equilibrate the System and Verify Operational Status
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.
