14 Agilent 7890 Series Troubleshooting
1 Concepts and General Tasks
Automatic Liquid Sampler configuration
Keep the Automatic Liquid Sampler (ALS) configuration
up-to-date to ensure proper operation. ALS items to keep
current include injector position, installed syringe size, and
solvent and waste bottle usage.
Gas configuration
Reconfigure the GC every time the gas type is changed. If the GC
is configured to a gas other than what is actually being
plumbed, incorrect flow rates will result.
To confirm the gas configuration:
1 Press [Config].
2 Scroll to the appropriate detector or column item on the
display and press [Enter] to see the type of gas configured.
Always configure the GC appropriately when working with
hydrogen. Hydrogen leaks quickly and poses a safety concern if
too much of it is released into the air or into the GC oven.
