Hi byoo,
Do you get any failed to communicate or any other message when you start up the software? You are correct if the busy light should be constantly flashing. This means you got a successfuk firmware load from the PC from ethernet connection. Can…
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
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…
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 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…
