Yes, it is off on all gasses, always by roughly 20% (occasionally nearly 30% or as low as 15%, depending on the instrument). Air, Hydrogen, Makeup (N2), carrier (H2 or He) on every instrument (12 GC and 3 GC/MS, which haven't been evaluated). It's 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 all
Apparently the engineer who did the mainboard replacement made a mistake by plugging the MCGV cable to the SSV cable, this made the valve failed to switch (EE 2040.2) and electronic fuse of SSV (EE2049.0) error always appear. It was out of my…
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…
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…
We have a brand new Agilent 6495 LC/TQ system with a MS 120 rough pump. We vented and shut off the instrument for building maintenance over the weekend. On startup today, the rough pump receives power (the lights turn on) but eventually fails to engage…
5 psi inlet pressure running hydrogen with your configuration leads to 2.3 ml/min to the MS and 1.02 ml/min to the FID.
You are welcome. Are you using a two-hole ferrule in the injection port or a splitter of some type? The two-holed ferrules are..…
Andy G. had the excellent suggestion to decrease draw speed and wait time, since we are working with methanol extract. So we halved the draw speed from 100ul/min to 50ul/min and increased the wait time from 2 to 3 seconds. For now, this seems to have…
Hello,
3-way valve is a good idea, but unfortunately all I had was several 5180-4160 Tee, 1/8 in, brass, and several 0100-2144 Ball valve, 1/8 inch.
So I decided to make following setup.
In the setup below I am using He as carrier gas and N2 as…
