Hello all I'm looking at designing some standby methods for my 4 GC-FIDs and 3 GC-MSs as they are often sitting idle for 3/4 days a week and are happily consuming helium, hydrogen and generally sucking money away basically for no reason. Turning them…
Dear Agilent,
I am using Agilent 6470A mass. Yesterday, I tried to check-tune it failed, and I have done auto-tune the results were okay. Again, I have tried check-tune today it failed and I checked with autotune. The error message popped up that autotune…
Aux 2 is typically configured as the transferline heater/sensor. The simplest thing is to vent the MS, turn off the GC, remove the column, slide the GC away from the MS, and then unplug the transferline heater/sensor connector, plug it back together,…
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…
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…
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…
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…
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
