We're having trouble in the 'coding' needed to get chemstation to make custom calculations for us.
Basically from our old software using chromcard the GC would report back area under curves. We would plug these numbers into an excel spreadsheet with the formula
Sample conc = (ISTD conc * (response factor)) / (amount of sample added * slope of calibration curve)
We measure short chain fatty acids from freeze dried faecal material. We'd like to take into account small variations in initial starting material.
I have set up a new calibration table on chemstation. However, this isn’t taking into account varying starting sample amounts.
I see that when generating reports you can add custom columns but I’m struggling to find the ‘coding’ used that what help me recreate this formula.
Its a pain as well with each run generating a separate page/sheet in PDF or excel so we have a macro to view all the runs in a sequence together. I'm sure i'm just using the software wrongly but it isn't obvious how else to do it
Thanks for any help!
