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…
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…
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..…
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…

There is an example of printing text instead of the final concentration based on the LOQ outlier in this discussion.

Is there a table / document somewhere on what Agilent GC FID flows I should be using for a particular column ? Right now I have a 7890B with a 30m 0.32 column film thickness 0.25. We use it for petroleum / Diesel Range Organic analysis with a ALS injector…
When trying to close a connection on an instrument with an active single run or sequence the OpenLAB CDS software will usually give a message that it will close connection when the runs are finished. Today when trying to close 2 instruments on the same…
Hi,
My baseline is around 8pA in standby state. H2 is coming from a tank and I can rule out contaminations in the gas source because the gas line is splitted with T piece: one is going to the FID EPC and one is going to the inlet PCM. H2 is the carrier…
