Answer Posted / godhani pragnesh
RRF= Relative response factor (Impurity response with
respact to main peak)
RF= Response factor (the response (e.g. peak area) of drug
substance or related substances per unit weight.
RF= peak area / concentration (mg/ml)
Relative response factor (RRF)calculation:
RRF=RF impurity / RF API
OR
RRF=slope impurity / slope API
