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…
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…
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
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…
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, 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…
External Device not ready. Is it an Agilent Autosampler? Which model? Do you have another device like a headspace sampler?
APG Remote. There is a cable between the GC and the MSD so that they both start at the same time. A remote start cable from another…
Hello, Software used: - MassHunter Workstation Version 10.1.49 - MassHunter Qualitative Analysis Version 10.0 - MSD Chemstation Data Analysis (can't figure out version, when I click the help button error message "failed to launch help" appears) I am having…
I am running on an Infinity 1260 II Ultivo LC/QQQ and have a problem when running check tunes. Every time I run a check tune, I get an out of tolerance result where the only parameter out of range is the gain factor. It fluctuates between being out of…
