I apologize, I want to ask you for help. I don't understand how to create a formula.
I want to create my own custom calculation to determine the concentration of budesonide and formoterol in a sample solution from the reference peaks in another chromatogram.
For example: The 2 peaks I have are budesonide and formoterol and their area peak.I need the calculated concentration of budesonide (peak area of sample solution / peak area of comparison * 100%) and formoterol (peak area of sample solution / peak area of comparison * 100%). These are two different formulas.
Any help with this would be greatly appreciated and save me a lot of time from manually calculating this in excel.
