Answer Posted / dixit kachhia
Potency = purity-(LOD/Water content+residual solvents+total
impurities+ ROI)
PURITY IS CARRIED OUT BY HPLC CHROMATOGRAAPHIC PURITY AND IS
%AREA OF MAIN PEAK where all peak integrated including all
known and unknown peaks due to product
i am not in favored of potency calculated on basis of assay
rather than purity because assay calculated against another
std and there will be a possibility of no. of errors in
define correct assay.
