The universal VUV detector has sensitivity better than an FID and similar to an MSD while allowing data acquisition across 12 different wavelength bands to focus on selected compounds of interest. It can be mounted directly on top of an Agilent 7890 or…
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…
Paul thanks for your reply. I have looked for information about these traps because I have two RMSH-2 traps and I thought about using one for the carrier gas (He) and the other for the FID hydrogen. Anyway, I'm going to buy the hydrogen trap. Thanks …
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…

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…
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
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…
