Thanks for the answer but I still fail to understand.
If helium pressure at the inlet of the TD is constant and only controlled manually, why can't it be controlled by the AUX EPC?
Can't I just connect one of the outlet of the AUX EPC through a t…
We fail to properly communicate with the turbo V70 controller, model 969-9507, using RS232.
The communication is ok for all commands that do not answer with more than two bytes, like start and stop.
However, commands supposed to answer with more than…

Hi community
we getting error message (Configuration system failed to initialize. Chemstation will shutdown now) when we trying to launch Chemstation ,we try rename conf. files in C:\Chem32\1 but that not work.
I appreciated any help .

Hi,
I get this Front Inlet: Septum purge Pre shutdown warning with Error code: 20401202 with cause showing EPC module is going into a shutdown. This warning showed up immediately after the maintenance was performed to change the septum and SSL liner…
Hi Everyone
This is my first post here in this community. And I really hope to get some ideas to fix my problem, since i'm getting slowly desperate!
So here's my problem: We have some really bad contamination/peaks on all our polar Systems:
I…

Hi JF_Fortin ,
As andyg mentions, starting with Qual B.08.00 SP1 and Version 10.0 the handling of data files with only 2D detector data has been improved to automatically open non-MS chromatograms.
In previous versions the message you are seeing is…
We have a GC-MS instrument and it works well. Recently we installed a new column which connected to FID detector. Now we want to run a method with GC-FID/MS. However, we observed the peaks only in MS spectrum without FID spectrum. We need help with the…
Hi,
this is a very nasty mass axis.
Could you please confirm, that you have S-Lenses installed, as they are configured.
Please have a look, through this troubleshooting guide and follow the instructions. Hopefully it will solve your problems, or…
