what is difference of uv and pda

Answer Posted / ananth

PDA - Photo diode array

UV- Ultra violet


with use of PDA detector, we can measure the area or height
of particular peak at different wavelengths ranging from
200 to 800 nm by injecting the solution at once. Where as
in uv detector we can measure the area or height of the
peak only at two different wavelengths. But that
wavelengths also to be selected before injecting the
solution.
