Would someone please let me know if it is required to determine RRF for impurity on multiple lots?
Thanks.

Hi

In my opinion your question is a tad to short and lack some information.

Do you for example mean RRF on different lots of the impurity or something else? Ie are you qualyfing an impurity?

Is your question pharmaceutical validation related? the ICH Q2 guideline deals with intermediate precision from a validation point.
