A sensitivity comparison was made between conventional atomic absorption spectrophotometry (AAS) and conventional molecular absorption spectrophotometry (MAS) for the serum trace metals, copper, iron, and zinc. The sensitivity aspect considered was absorbances was obtained for concentrations in the solutions analyzed using unit lightpaths of 1 cm and 10 cm for MAS and AAS, respectively. A disti...
Spectrophotometric method is often recommended in dissolution testing of not only tablets or capsules but also suppositories. Dissolution rate of diclofenac sodium was studied using a pharmacopoeial flow-through apparatus and pH 7.3 buffer. For two lipophilic suppository bases (Witepsol W-32 and H-19) dissolution rate was overestimated with the spectrophotometric zero-order method in comparison...
