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…
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…
Hello Agilent Users,
Im missing a feature in Openlab since day 1. How do I override and start a run if the GC is not ready ?
For example: the FID temperature is set at 250°C in the method and the actual temperature is at 220°C (it is still heating…
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…
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…
Canadian_Chemist ,
There is an example of printing text instead of the final concentration based on the LOQ outlier in this discussion.

The GC counter rolls over at 999,999...but 100,542 is still a lot!
Great drawing, thanks. That setup makes it difficult to figure out pressures/flows. The path of least resistance is all of the 530 pieces unless the methanizer and the connection from…
The idea behind the multiple modes is to keep the flows going through your FID constant. Changing flows will change the flame characteristics and cause the baseline to shift. Some suggestions:
If your column is set to constant flow mode, use "Constant…
