LC Injector HTC/HTS Description and Installation
Troubleshooting
Avoiding Trapped Air Bubbles
It is common practice to make a connection only if the ports are wetted. The
liquid helps to prevent trapped air bubbles which are often very tedious to
remove or work out of a system.
Solvent Delivery Pumps are not priming
It has been observed that the solvent delivery pumps of the Pump Module can
fail to prime at initial operation.
The pump has to be wetted at the solvent inlet port, or preferably prime the
tubing from the Solvent reservoir to the pump and make the connection.
Dry running the pump for a short time will not harm it.
