William Letter

Add peak areas to find total. Divide area by total to find percentage.

Massoumeh Farasat

You can use this link to calculate the peak area.

Haresh Kalasariya

Massoumeh Farasat I have calculated accordingly, will you please check the below-calculated results. (Excel file, sheet 2)

I am also attaching the Chromatogram report, PFA.

Yuhta Nomura Thanks sir, I have a chromatogram report, PFA

Your suggestions are highly valuable to me

Method quality is questionable so results obtained may be invalid. Area counts are also inaccurate because the integration parameters have errors. Correct your integration (or method) before moving forward. *As shown, your method and results are invalid.

I agree with William.
