Answer / d.thirupathi
if the method dont have known impurities we can choose the

can go for w/w method

Answer / parag
we can go with area normalisation method when the RRF of
the impurities are 1 or during the Drug-Excipient
Compatibility study when the amount of drug added in the
sample not exactly known concentration.

Answer / naga
when all impurities RRF values between 0.95 to 1.05 we can
go for area normalisation method
| Is This Answer Correct ? | 3 Yes | 3 No |
Answer / tukaram masal
When response of main peak is linear from LOQ to nominal
test concentration then area normalisation method for
related substances and When response of main peak is not
linear from LOQ to nominal test concentration then w/w
method for related substances.
