What are the advantages (or disadvantages) of using a UV-diode array
detector?
Please take pity on this student!
The advantages of a PDA detector over a single wavelenght UV
detector is the acquisition of absorption data for the analytes over a
range of wavelenghts, thus allowing the acquisition of a UV spectrum
for each peak, which can help with identification and on the
evaluation of peak purity. Among disadvantages of a PDA is that
usually they are less sensitive than a single wavelenght detector,
although recent developments in flow cell design have partially
overcome this limitation.
