How to calculate LOD & LOQ in HPLC Validation Method

Answer Posted / rakesh p. kotkar

Based on standard deviation of the response and the slope
obtained will be calculated as:

Limit of Detection (LOD):
DL= 3.3(ASD/Slope)


Limit of quantification(LOQ):
DL=10(ASD/Slope)

Is This Answer Correct ?    10 Yes 3 No
