EPC replacement

Hi CM Zainea;

 It is a 7890A with headspace. The EPC was replaced since the GC does not reach the pressure set point. After the EPC replacement I need to challenge the GC in order to demonstrate that the equipment is operational. Is there any test that proves that the GC is working correctly after the EPC replacement? (Ej. a pressure test or a system suitability)

Hello Grisell ,

There is a leak test you can run on the inlet. I am assuming you are using a Split/Splitless, and the procedure is below:

Using the 7890 Service Mode Leak Check (agilent.com)

Let me know if that answers your question.
