Hi all,
One of my GC ms sensitivity is very low. 10 ppm organophosforus std its giving 900khz only for 1ul injection.Splitless injection .
In diagnostics RF is failing saying like RF DAC cannot convert value above 56 .software suggesting RF generator board faulty .replaced RF generator board but its giving same message in diagnostics. I also changed main board
but there was no progress. Air and water is normal . calibration is passing . trap calibration is failing..please advise .
We had a similar problem and it was caused by the small square daughter board attached to the first board you see when you remove the side cover. Using a fan to blow on it and just gently touching it would make it work.
The past is there to guide us into the future, not to dwell in.
