There already IS an interfering mass program in ISODAT, but only in ISODAT
NT 2.0

Here are the instructions I got from Jim Burdett about setting up
the isl to run interfering masses in Isodat 2.0:
-----------------------------------
-open the acquisition.isl
-add the line "include "lib\InterferingMass_lib.isl""
-add the line "call DiMeasureInterferingMasses(Ms_PeakCenterChannel);" where
you want to measure them

Example:

...
//-------------------------------------------------
include "lib\math.isl"
include "lib\stdisl.isl"
include "lib\instrument.isl"
include "lib\DualInlet_lib.isl"
include "lib\InterferingMass_lib.isl"
//-------------------------------------------------
function CleanUp()
{
}
//-------------------------------------------------
function InitScript()
{
  OnBreak CleanUp;
}
//------------------------------------------------
//this is the main point entry - this function is necessarily
//-----------------------------------------------
main()
{
        call InitScript();
        call DiMeasureInterferingMasses(Ms_PeakCenterChannel);
        call PeakCenter();
        call Background();
        call Pressureadjust();
        call Acquisition();
...


-----------------------------------
The existing library file can be found at:
C:\FINNIGAN\ISODAT NT\Global\ISL\lib\InterferingMass_lib.isl

Make sure the acquisition.isl file which you open and modify
in the instructions below is the one referenced in the
method you will be using! (There are multiple acquisition files)
And of course, save a copy of the original. (Dont ask me how I know this)

The result is a new window tab in your method... ISL/Interfering Mass.
Works fine, It's easy to add more than the default 5 interfering masses.
But mine always runs on the standard side.

NEXT STEPS
Has anyone already done any of this?

1)Add dialog box to Int.Mass screen to choose SA-ST for each mass.
This will allow gas ratio determinations. I can add a box, but cant figure
out how to make it interactive.

2)Get Int.Mass results to appear in Excel output.
