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..…

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…
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…
