IN THIS CASE INCRESE SAMPLE CONCENTRATION EG; MY DRUG KNOW
IMPURITES LIMIT IS 0.05% UNKNOW IMP LIMIT IS 0.03% INTHIS
CASE STD PREPARATION IS 5MG/100 FURATHER 1/100 THIS IS KNOW
IMPURITES CONCENTRATION 3/100 AND 1/100 THIS UNKNOW IMP
MEANS API, SAMPLE CONCENTRATION IS 1MG/ML IF STD AREA IS
NOT COME INCRESE THE SAMLE CONCENTRTION MEANS
10/100*1/100*10/20*100=0.05% SAMLE CONCENTRATION IS 2MG/ML
