Help setting up existing GC-MS for Drug Analysis EPA

Hi all, 

 

Our dedicated drug quant GC-MS has finally given up, so as the title suggests I'm setting up an existing GC-MS to run drug analysis for nicotine, with the hope to use /Drug Analysis/EnviroQuant/EPA using ChemStation. It currently runs in 'Enhanced' mode. 

 

I have been through the GC-MS Configuration tool, but when I go to select the Workflow Mode, it *only* has Enhanced mode to select in the drop-down. Normally I would check the existing PC controller for the old GC for the setup parameters, but when I try to load up the configuration on there, the PC freezes and the program doesn't open. I am using the attached setup workflow guide

 

Is the lack of Drug Analysis/EnviroQuant/EPA a software error, or will I need to re-install/re-configure anything from there? 

 

Thanks in advance for any help!

  • Go ahead on configure the instrument as enhanced. Then in c:\gcms\msexe find the file msdchem.ini and make a backup copy of the file. Open original in Notepad. in the [PCS,1] section find the line that reads

    Application=1

    if you want drug mode make it

    Application=5

    If you want Envquant mode make it

    Application=2

    Save the file but do not do a save as. Start software and should be in correct mode. If you reconfigure the instrument you will have to modify the file again.

    I have only seen this once, and if I remember correctly this is how I got around the issue.
