no you don't need to disconnect it from the FID, ,
bake the column for enough time usually more than 1 hour according to your column status , you can keep the FID working to monitor the baseline .
..
keep temperature 25 degrees less than the maximum…
Using the Agilent 7890A. Column installed with no leaks detected. Both the front and back detector are set to 300°C, gas Flow Rates - Hydrogen: 45mL/min, Air 450mL/min and He 1.0mL/min. The split flow is 80mL/min. Following initial start up the front…
Thanks for the tips on seeing the position in the sequence once Aquisition has been restarted. Unfortunately something I failed to mention is that the sequence also disappears after pressing run but will re-appear once you toggle between another module…
Hi all, I am using a GC 6890 with split/splitless inlet to analyse reaction products. However, a problem has recently happened when the GC is running. I have noticed the appearance of spikes in the baseline of the FID detector. The spikes appear occasionally…
Get a WS asynchronous error : F F60304 The torch ignition has failed when starting a Varian 720 OES The torch lights and stays on for about 5 seconds then shuts down with this error. I can not find reference in the help to resolve this. Thanks, Scott
Hello, im having a problem with a 2d GC using the Deans Switch system. Its a 8890 GC with 2 FIDs. The problem is that, when cutting peaks from the 1st dimension to the 2nd dimension (2nd column), all peaks on the 2nd dimensions get split into 2 peaks…
Hi John, You are on the right track-- it sounds like your flame is not lit. The reading you are seeing on the Hydrogen line is likely back-pressure from the column flow. That result could indicate a blockage in the jet, but the flow is a little low to…
It looks like it is having to clear something out the inlet, column, detector or head space as the baseline rise is over most of it. I see it's a FID you are using, how long do you leave it ignited before running the first analysis?
Hi all,
I'm using a 0.18 mm HP-5 GC Column on a Shimadzu GC-2014 connected with a FID. I'm looking to get new ferrules (the old ones had been passed down from previous users) and wanted to discuss some options. I tried using some 0.5 mm graphite ferrules…
Hi, I have a agilent GC 7890B with FID. currently i am a facing a problem regarding this GC, problem is like that - all gases supply is ok, no leakage is found in detector portion. i have cleaned the FID & Jet but flame is not burning. So kindly suggest…
