Answer Posted / ajinkya p.
In pda detector light from UV & D2 both combination first passes from flow cell & then grating so we get array of light so we check absorption for each wavelength And also facility to calculate peak purity ( if there any hidden peak behind the interested peak)because pda has 3D view. In UV detector light from uv first fall grating & then flow cell, and we can put only known single or double wavelength at a time to analysis. this is the diff. between pda & uv detector.

what is the purge flow & how to calculate
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.
