I have an Agilent 7890A with a split/splitless injector and FID. The FID has been experiencing a falling baseline signal that triggers the instrument to relight the flame unless I lower the lit offset value. As it gets worse, I have to set the lit offset…
HP 5890 II not responding. After power-up, initiates "Passed Self Test" routine but stalls at that point. The oven works, and FID is ignited but the light by "Not Ready" is lit up. ChemStation program states: "GC Not Found. Check that GC is Correctly…
I met same error while installing CDS 2.7 on Win 10 pro

Hi, I am wondering if the FID detector requires nitrogen make up flow while in standby mode or is it sufficient to have the FID idle at a temperature above 100 to protect it in downtime.
Thanks.
Hi all, we have Error "1467: Option gas flow rate is out of acceptable range" when trying to ignite the plasma. But the thing is, we don't use option gas (we are running in laser ablation mode) and have nothing connected. We think it might be related…
Hello
I wish if i can find solution the this problem
I don't have access to ignite plasma because after i turn on chiller ( Temperature the peltier it ouside range -40 ± 2 )
some times take -52 C or more .... ( i notice there are not value exact…
I use a 8890 series GC with MSD, FID, TCD. Splitter from column to MSD & TCD or FID Multimode Inlet. 30m DB-5 Column. MMI 325C, FID 325C. 10 C/min ramp until 325 and hold for 15 min. 45 min run time It's 98% used for QC using TCD & MS. However there is…
Hi, Have this issue with an Agilent 6850 GC: The system performs normally during the pre-run: the oven temperature, front inlet total flow/inlet pressure and signal 1 valve values are all normal/stable. When we switch to the test method and start sample…
Hello, i get unusual high signal on FID on 7890 and this message
"Front detector - Fault high voltage error"
What is happening? There is some part I can try to replace before call a technician?
Thank you
