Hello,
A question:

I'm validating an UV method (sample preparation involves a precipitation reaction) and i notice that this method is not proportional. It is linear in my range and when concentration is 0 (specificity) i have no response; can this method be validated the same?i think it should be possible according to ICH guidelines but what's your opinion?

thank you very much

Can you elaborate on what you mean by "not proportional"?
