EPA 524 saga continues. I am covering volatile section after one of our chemists quit, and we re are in the process of transitioning from chemstation Enviroquant (which I dearly hate) to MassHunter EQ. Right now, tt appears that our MassHunter Enviroquant (10.1) is referencing wrong data files for CC calculations for EPA 524. We run 8 point curve from 0.5 to 60 ppb, and CC’s at several different levels (10, 0.5, 1, 2 and 5 ppb). First off, the mid response is referencing 60 ppb file, instead of the 10 ppb. Also, the area % seems to be calculated against 20 ppb instead of 10 (in the case of attached report below). During the acquisition setup, I assign cal levels, and also the CC levels. At this point, I cannot use this software for compliance reporting.
On a side note, I also have MassHUnter (older version, I want to say 8 but I am not the instrument right now) on my 7000QQQ that does not exhibit the same problem (I use it for EPA 521 and have 7 point cal and 2 CC levels 2, 50 and 100 ng/L and all are calculated correctly).
I know that MassHunter is using python for task automation so perhaps the subroutine needs to be looked at. Is anyone from Agilent reading this who can help?
