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…
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…
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…
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…
I have started using GC-FID (Agilent 8890) since March for the first time. We are trying to measure the methane. I was trying to make a standard surve, so I injected 1000 ppm methane standard at first. Just to let you guys know no samples has been run…
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…
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
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 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…
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…
