Hi there. I need your help. My gas sample is including hydrocarbons, CO and CO2, I was told I should used TCD detector, I used but there is no peak. I believe I need to use both FID and TCD detectors at same time and for that I need connector series between…
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…
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…
Column: HP-PLOT/Q+PT 30M +5M Duraguard (2.5M on either end) 0.530 mm megabore, 40Micro film Primary components residual EO and PO in various acceptor chemistries. Separate STDs for each, both are showing area decline, on FID, recently switched out flame…
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…
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…
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…
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…
