Hello,
I have GC-FID 8890 and there's problem is suddenly appeared, the increasing shift in retention time for concentrated samples and for some of diluted samples that I previously injected and the retention time didn't have any shift.
Please consider…
Hi,
I get this Front Inlet: Septum purge Pre shutdown warning with Error code: 20401202 with cause showing EPC module is going into a shutdown. This warning showed up immediately after the maintenance was performed to change the septum and SSL liner…
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…
When I need information about detectors I use the following books:

Hi GeorgiaDean were you able to solve your problem?
In regards to the FID not lighting, be sure to refer to the Troubleshooting an FID not igniting article in the Knowledge Portal.
Hi everyone, A few weeks ago in our lab we installed a new inlet/column/detector set-up on an existing 7890B GC in our lab. This GC already had a front inlet/detector installed and there was never anything installed on the back components. Therefore we…
Hi, I would suggest to test the same without column installed to the FID. If problem looks similar check for leaks at the FID gas lines and clean the FID. If not clean the inlet and replace the split vent line and filter. Maybe try a new column.

Hello, I am injecting ethanol samples by direct injection which contain trace amounts of methanol and notice the methanol peak varies injection to injection on the same sample. I also injected pure air (empty vial injection) to find out if there is something…
First make sure that the air supplied to the GC is at a high enough pressure. Typically for FID air it should be at least 60 psig (4 bar), maximum 120 psig (8 bar). If that is okay, the EPC module should be replaced. Part number for 7890 FID EPC is G3431…
