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 vitiin96,
this is very generic and any book on GC troubleshooting or the videos on the Agilent website could help. For the 7890 there is a troubleshooting manual available.
Good practice in GC is when you get a (new) column, you have an own suitability…
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…
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…
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, I'm working with a LC Infinity Lab 1260, which has a standard autosampler and 100 uL loop. I'm trying to achieve a very simple injection program, but keep failing. All I want to do is to draw 50 uL from a sample vial, 50 uL from a second sample vial…

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…
