In my experience, usually when a method fails to download to a 7820A GC it means that one of the zones on the GC is in a faulted state. This does not always get reported in the instrument actuals in ChemStation, so the best way to double-check this is…
Hello everyone, This is my first post and I'm excited to have discussions for this thread. I wanted to start off with a small introduction with some of my experience. I have 4 years of experience in operation, maintenance, method development on the following…
Hello,
We have a GC 7890A model equipped by tray (SN#CN90452624) and Autosampler (SN#7683) I am receiving the following message while trying to run sample followed by a shaking arm and beeping noise. Any help on what might cause the problem is greatly…

It knows that the electrometer board is plugged into the main board and expects everything else to be there, too. The simplest suggestion is to power down, unplug the GC from the wall, remove the FID electrometer from the main board, button it back up…
Dear Agilent,
I am trying to perform a "backflush scouting run", using the nice backflush wizard option in Chemstation rev. C.01.10, for configuration of a useful backflush time to my GC method. However, the backflush wizard unfortunately stops after…
My GC-FID says the following when I change the split ratio form 50:1 to 200:1: Front inlet flow limited. I dont know what I need to change further so it won't be limited. Does anyone have some tips
Hi chemist85 , I'd like to inform you that our instrument problem was solved, and yes it caused by the broken UPS, the output voltage is dropped to 160 volts when igniting the plasma, and also the voltage was not stable at all and unfortunately, it also…
Good day Agilent, I am really humbled to join the community. I have a few inquiry I would like to make.
I am having a very noisy baseline every time I try to bake out using both ECD and FID,
When I analyze acetaldehyde using the FID it keeps the noise…
Hi.
So ive had a very high sample with Methanol (around 8000 mg/l) and now i still have contamination around 500 mg/l in my blanks. Ive tried injecting IPA and replaced the syringe. Any other tips? Ive also pumped up the oven/column tempature to a…
