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…
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…

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…
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…
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…
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…
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…
