Thank you Rafik Sir, butbut i have done GC-MS for crude extract without any standards. i want to find out the compounds present. how to calculate peak area percentage without standards.
What do you mean by peak area percentage? Can you be more specific or explain your doubt and problem to: [email protected]
From BARC, Mumbai, India
The following link illustrates the method to calculate the peak area percentage in GC which is the same as for GC-MS.:

Hoping this will be helpful,
Mrs/;iss Ulagesan,
By curve-fitting approach.
Agree with everyone's view. Especially, Rafik's Sir.
Its very easy to me
