IT IS DEFINED AS PURITY OF A PERTICULAR PEAK THAT IT IS NOT
COELUTED WITH OTHER IMPURITIES
PURITY=RATIO OF ABSORBANCE B/W THE ROOT OF UP SLOPE AND
APEX/RATIO OF ABSORBANCE B/W THE ROOT OF DOWN SLOPE AND APEX
IF THE PURITY=1, PURE PEAK

How you develop a method in HPLC?
For standardization of volumetric solutions, acceptance limit for concentration is considered as 10% of nominal concentration and %RSD as NMT 0.2% (for appropriate no. of replicates). But , if %RSD has not met, what should be further action?
