Hi azrael, The FID is not a pressurized detector so there is no pressure test. You may wish to explore our GC Fundamentals series on our website. See Below for a link Fundamentals of Gas Chromatography (GC) - Part 1 | Agilent Regards James
Hello,
I am having an issue getting the system pressure test to pass. I have referred to the manual and followed all the steps, and have checked for any leaks (there are no visible leaks) and the leak test on the system is also passing - yet the pressure…
Hi This morning the check Tune failed. After adjusting MS1, the tune passed with warnings. Then I decided to autotune. It went through many of the steps until "Enhanced" failed. I am not sure what this step is. Not easy to find any documentation. Can…
We have a 7890B that was configured with an MSD but is being reconfigured for a different analysis. It is now running an FID/TCD method, and the aux detector has been disconnected and unconfigured. The MS/Aux Det button on the GC keyboard says no aux…
Hello everyone
I have 3 error messages from the Agilent infinity ii 1260 SFC Multi sampler:
1- Metering device Movement Failed ( EE25444.0) 2- Taking needle From park station failed ( EE25105.201 ) 3- Axis did not reach its target position in time…
Hi, I have the same problem as well. We are using LC 1220 Infinity series. We tried flushing the system with isopropanol for 10 minutes just in case the bubbles are present. However, this does not solve the problem. The pump failed to get ready within…
When Air gap is 0.2 and the flow rate is 2.1 ml/min then the peak area found 287 by FID but when the air gap is 0 and flow rate is 1.47 ml/min then the area reduced to 141. Where analysis performed by Autosampler.
I think we do this at my lab but not with a valve. We use a plot column and anayze headspace above a water sample. We test for methane ethane ethene and propane useing an FID. The integrated gastight syringe with a valve in it from Fisher helps. We use…
Hello everyone, I would like you to help me with a genesys 30 spectrophotometer, I have a problem that says: * Zero-Order search failed
psdt: I have already changed the focus for a halogen one but it only reads from 500 nm but at 325nm it does not read…
Using OpenLab EZChrom A.04.1.0.0 with a 6890N GC-FID this error occurs
The IS dept have looked into this and have commented that the systems log mentions that the instance has reached its maximum size of 32MB. We have been running the same system…
