Hello,
I am not entirely clear on what you are doing as well. Below is an example of how I would do a % recovery from an existing standard injection in the result set. The calculation would pull the theoretical value (Compund_CalibrationAmount) from…
Hi JONHY , thanks for your question.

Hello,
I think there are other posts where I go over this in more detail. If you want to do a recovery or check calculation for more than one compound and it is not a reinjection of a standard level or the standards are not in the results set, the…
Hello,
Yes, that will not work. You need to test the length of the name as I said in the previous response. See the example below the unknowns have a low value of 1.56.
if(LEN(Compound_Name)>0, getconstant(“Relative response factor”),0.98)
…
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…
