I HAVE GCMSHES 5977B ; during TUNING ;IT GIVES tune action stopped :MSD Fault 2 : RFPA Difficulty . WE try cleaning the ion source , changing filament but still the message appear
how can i resolve this?

how can i resolve this?
many thanks for all persons spent their time to reply me about solving the problem
the problem solved by changing quad and quad driver by Agilent regional represent
but i have a notice that through explain my problem no one from Agilent engineer give me a remarkable advice to track the problem .
my advice to all people to track this problem to inspect the quad and if any black colour appear inside the quad this means the quad need replacement
The quad is not a replaceable part on a single quad GCMS, the analyzer should be replaced as an assembly. There is a long explanation about black marks inside the quad, but suffice to say that it is all sample residue of ions and unionized molecules. It can be exacerbated by air leaks, column bleed, bad gas, and the way the operator is running the system.
many thanks for your replay , i tooled what happen exactly, and i agree with all your above points
Hi, I am getting same message. But auto tune and quick tune report both are very good. I am getting "RFPA difficulty" message during tune evaluation. How to solve this?
Durjoy123 would you please start a new forum post with your questions? Please include as much useful information as possible - instrument model number and age of the system, MassHunter Acquisition software version, which high vacuum pump type, the vacuum readings, which ion source, which tunes, what carrier gas type, column type, gas flows, sample type, number of runs on the system, etc. You can share tune reports and a screen capture of the RFPA difficulty message, too,. ....in short all the information that may help get you a good answer quickly.
