GC Not Ready Symptoms
GC Never Becomes Ready
60
Normally the GC becomes ready after flows and
temperatures reach setpoint. If the GC does not become
ready after a long period of time:
• Press [Status] or a component key (for example, [Front
inlet]) to see which setpoints or conditions are not ready.
• Check for a sampler problem.
• Check for a data system problem.
• If performing manual injections in splitless or gas- saver
mode, you may need to press [Prep Run] to prepare the
inlet for the injection. Do this, for example:
• To toggle the inlet purge valve before a splitless
injection
• To prepare for a pulsed injection
• To turn off gas saver.
For more information on [Prep Run], see the Agilent 7890A
GC Advanced User Guide.
