when we use pda detector in hplc instead of uv detector
Answer Posted / ramkrishna thakare
1)PDA- IS multi-wavelengths detector.
2 ) PDA- shows (3 D Images)3DIMENSIONAL STRUCTURE. so that
peak purity can be detected.
3 ) isomerism can be find out.
thats why PDA USED

In BP2013, Loperamid HCl monograph. Assay by titration with 0.1N sodium hydroxide using hydrocloric acid 0.01N and reading the volume added between the 2 points of inflexion. I have a question that if the diluent solvent is ethanol is certainly consumed a amount of volume of titrant, so this volume must be eliminated on the result calculation or not apart from first point which is subtracted above.
