Best Way to Find % Active

Hello all. I'm very new to OpenLabs CDS and my 7890B GC, so apologies in advance if I don't phrase my question well. I want to be able to find % active of an active ingredient but not sure if I need a custom calculation to be able to print onto a report or if I can accomplish this with just a calibration curve. Trying to move away from putting all this information into an excel spreadsheet manually. 


  • Hello,

    That looks like a standard IS calibration using area percent. The purity of the standard can be entered as the compound multiplier. I would start by searching the help for calibration, internal standard, and mass percent calculations. You can also look at the attached guide for the same information.
