Thank you for all your suggestions, this is what I have done so far, With computer disconnected from our Network (to eliminate firewall issues, as per recommended by or IS/IT department): Both instruments connected through hub - failed Only 6850 connected…
I am new to Agilent forum, We got a new GC 7820 with FID detector. I am using Open Lab CDS chemstation Ver 2.2, if you upload video turorials for this version that would be really helpful. For your information I got about e familiarisation disk, but I…
Hi, Thanks a lot for your great help. However, how to use "Import worklist" function to import entries into the user defined " Amt. and Tot. Amt. " column? Other info are import succesfully except the two ones. I tired " Amt.","Tot. Amt. " in the importing…
Hello Guys, I am using Agilent 7890a GC with an FID detector. Last week I saw that there are few ghost peaks in my chromatogram, so I decided to bakeout the column. After baking the ghost peaks disappeared but now I see and increase in the peak towards…
Hi, There are so many open questions, that i would ask you to run thorugh the "Troubleshooting Tool". It´s an guided pdf, which helps to identify the problem. The last performance report looks quite well, also the torch axis and the em tuning run without…
Hi galderson,
that's a typical "it depends" answer. For the carrier gas line I assume you use at least a 5.5 or even 6.0 gas quality? Anyway depending on the gas quality there are different concentrations of impurities:
Now you need to…
I have GC-7890B -TCD -FID . I want to maintain the flow of gas sample to be same as calibration gas flow . Are there any option in GC to give same flow of sample and calibration gas or shall i use flow meter at the outlet of GC .
Thank you for your help, Paul. I'm not sure what happened on October 27. Many people use this system.
This morning, the system passed the Tune Evaluation, but the HiVac is still off. I looked at the Manual Tune task box, but do not see where I have…
Thank you James, The software that we have, runs in a very old HP computer with Windows 2000 PRO. The equipment´s software only runs in this computer and it has had many fails lately. For it reason, we would like to buy an updated software that it can…
Dear Royboyle, Thank you for you email, i am still having issue with peak purity at 50% sensitivity the peak purity of standard is failing and when i change the sensitivity to 40% then it passes, i am bit confused now what is the standard guideline regarding…
