Purity indicates existence of of required compound rest of
other components(impurities) in a sample matrix.

Potency indicates the strength of required compound rest
of other components(impurities,MC,ROI, OVI,etc) in a sample
matrix. This potency correction is useful for the weight
correction. This gives the exat weight which we taken.

Answer / sai

Purity means- it explains how pure our analyte is in the given mixture. It is not related to the how much our analyte is in the given mixture. i.e  percentage of our analyte without impurities in HPLC (i.e known or unknown)  

Potency means-  it is measurement of our analyte  how potent it is.  i.e  purity of our analyte without all possible impurities like chromatographic impurities (HPLC, GC-Residual solvents, TLC), Heavy metals etc..
