Dear Community Member,
I have facing some issue in ELECTRONIC PNEUMATIC CONTROLLER (EPC) of GAS CHROMATOGRPAH (7890B) The EPC Module has not give the Set Flow rate for AIR Flow, as we have give the Set Point of Air 350 ml/min, but the observed flow…
I am looking to set up in line sampling on a GC/FID (6850A, G2630A) with a capillary column. I have found sample valves listed for 6850 series GCs (e.g. G2668A), but the part description specifies it is for G2630B, so I take it that this is incompatible…

After some burner head cleaning, I reassembled my FAAS 240FS and now I can't get the burner head to light. Some details:
I was running some "dirty" samples with the nitrous burner head that plugged up the sample capillary and started to block the…
The MS column exits into vacuum. The FID column exits to atmospheric pressure.
Same carrier gas, column, oven temperature, inlet pressure results in different holdup times. These examples are using the Pressure Flow Calculator available here GC Calculators…
Our Ultivo LC/TQ fails autotune immediately citing a Nozzle Fault. The log suggests the associated voltage is out of optimal range. Funnily enough, the system passes check-tune without any issue! The check-tune report shows the voltage perfectly matching…
I'm trying to install Openlab CDS 2.7 on Windows 10. When running the system preparation tool, everything passes test except the Ports Check -configuration: 'workstation ' and it says FAIL. I tried to run the recheck and repair, but it still fails. Any…
I was experiencing ghost peaks in my water blank shots so I decided to do some maintenance. This included a new S/SL liner and septum, removing the first inch or two of the column, FID disassembly and ultrasonic cleaning of the jet, and reassembly. Now…
The probability of water precipitation is very low if the FID temperatures are high enough, but in times of 5890 the FID could not ignite well when water was present. In principle a FID can be operated without makeup gas, which manufacturers officially…
