Could you please give me some suggestions on how (if possible) to validate an HPLC method that gives results in Area %?
I was asked to execute a validation of this method. There is no reference std whatsoever of the impurity I have to detect and quantitate in area %.
Nowadays, this method is used. The impurity quantity is given in area %.
I think that one can’t execute any linearity test or accuracy if doesn’t have a reference standard available.
Thanks a lot for your kind help.
