I want to use the dual inlet for reference gas injection when using the
gasbench and also the TC/EA on a MAT 253. I have been able to set up the
configurator for a gasbench+dual inlet and have added the "reference"
scripts for opening and closing the dual inlet changeover valves. This works
great. However, the beam intensity of the reference gases drops quite a bit
after 12 hours. I would like to be able to have the beam intensity from the
dual inlet remain constant over 12 hours or more. For this I need to get
Isodat to adjust the bellows pressure before each run and I am clueless as
to how to set this up. Is there anybody out there who is using the dual
inlet for reference gas injection and has figured out how get the instrument
to maintain a constant pressure in the bellows throughout the day? I know
you're out there!



Thanks for any help!
