Dear Agilent, We are at the moment experience trouble regarding initialization of Chemstations rev. C.01.07 [27] to 7890B GC`s on a couple of Windows 7 computers. Please see attached message box. We are able to ping both 7890B GC instruments. In config…
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…
Hello, I am having the same problem when trying to log into Chemstation: Configuration system failed to initialize. Chemstation will shutdown now. I have tried to rename or delete the user.config as explained before (following the Win7 steps), but I cannot…
Good day, Wondering if anyone can help as Agilent phone support will not. Trying to install OpenLAB CDS Chemstation C.01.07 SR3 onto a Windows 10 machine (their support did tell me that version is supposed to be supported on Windows 10). But when it tries…
I think it is something linked to Excel. I was able to turn on the alerts for the log so the basic program is working but trying to open the log fails with no errors. Starting acq does create a popup that it failed to write to the log but every thing…
Hi all, we have problem in GC7890B ,we cannot connection to the selected server and we try : 1- restart pc. 2- check Agilent open lab shared services it is started status. 3- change cable from straight to crossover. But the problem still exists. your…
