Hello dear all
I am working on analytical method for determination of excipients content (assay) in emulsion (O/w emulsion).
I have developed method for assay of it..but for validation I have to prepare accuracy sample in placebo at 50,100, and 150 level.
My problem is placebo of only API possible as per formulations but placebo of excipient not possible due to it's requirement for emulsion formulation.
Then how can prepare accuracy sample for accuracy study?
