UV-Vis spectroscopy is a well-established technique in many laboratories. For decades, laboratories have adapted to pain points associated with UV-Vis workflows such as daily instrument warm-up, yearly lamp replacement, and slow and cumbersome temperature…
Timmas You are running 7890A GC/5975 MS/ E.02.02 SP2 ? --- That version of MSD Chemstation was released November 2013 on Windows XP Professionals with SP3. The KBR error/fix you reference is from a document that does not support MSD Chemstation E.02.02…
Thanks Linh and Martin! first of all, it was not enabled in the instrument configuration. After the reconfiguration with intelligent reporting, I can see editing option! Also that course was very useful to me! Thanks a lot both!
I am having a similar issue. First, I replaced a needle seat and then the auto-referencing failed because I failed to recognize that the black sample holders needed to be removed. The needle mechanism seemed forever stuck in the parked position. I was…
Hello,
I am not sure what you did in your test, but it seems the alfresco instance is not running. The simplest issue might be the licensing if you renamed or changed the MAC on the VM guest.
