Thank you!! The firmware has been updated to D.07.35, forced cold start was performed and neither one worked.
As per service note I removed the sample handler and cleaned the X-Y rods with lint free cloth and IPA, re-installed the handler, cleared the…
Thanks for the help, What I failed to mention in my poorly worded initial post is that the issue was trying to bring our instrument up in standby. I had vented it, thinking we would store it this way for some time. After having done so, I was informed…
Hi, exactly what you said and like what Lance Nelson pointed out,the septum purge flow cannot set on GC 6890 but we can control the septum flow by reduce split vent value or split ratio ,so you can reduce split vent value in method 1 from 197.1 mL/min…
Hi Anatoly,
if the vapour pressures of the solvents are comparable it doesn't matter that you inject different solvents and even if they are very different like water vs. any organic solvent, the error is small.
In direct injections and cold-on-column…
Hi fabiotestoni , From the log file it appears the issue is with one of Qual's dependencies, SQL Server Compact Edition [09AC:06F0][2020-03-11T21:11:48]i301: Applying execute package: SSCERuntime_x64, action: Install, path: C:\ProgramData\Package Cache…
Hi Mike,
Thanks for the reply but i have run the instrument performance test it was ok.
Customer is using quarts cuvettes.
another issue we found when running wavelength accuracy and precision run from the validation, it missing one or two wavelength…
I am using Chemstation to automatically export 7890A and B GC-FID single page reports to PDF at the same time as printing a hard copy report for each injection. If I go into the data analysis software later and reintegrate my peaks, the software doesn…
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…
