Hello E_Johnson ,
I’m sorry for the delayed reply to your message.
Thank you for asking this question. Always refer to the applicable Agilent instrument safety information when performing instrument maintenance or repair ( 7890 Series GC Safety Manual…
I'm using the GC6890 with one single column (CP7429). The gas products have to be analyzed by TCD and FID simutaneously. How should I connect the column to TCD and FID? Is it necessary to have a s plitter to split effluent from a single column to TCD…
Hi
Check ALS and MS are ready or not..If ready and still problem then check cable from backside of GC as well as check cable communication hub( if used )..
I remember hearing about a big cost saving in air / hydrogen when the 6890 came out.. There was no way to shut off the 5890 gc gaases at the end of a run. I think it was about 5000 a year if you shut off the air / h2 / makeup gas at the end of the run…
Hi I am new to GC Method development phase. We are having GC 7820 A with FID detector. Currently I am developing a method for industrial solvents. When I run a blank (THF), I got a very unusual spikes in the chromatogram as seen below. I have changed…
I am using an agilent 7890B GC ECD system When i tried to open the Open Lab control panel, " Autostart Macro failed error#41063" was displayed and the control panel did not open. I tried your online solutions for similar error 16289 (Renaming for config…
I'm hoping to remove an FID detector from a 6890N to a 7890A. I noticed that the back panels for these instruments are different. Is it possible to move the FID into the newer GC? Will some sort of adapter be necessary for the flow control manifold?
