when we use pda detector in hplc instead of uv detector..

Answer / bujji reddy

1.PDA Stands for PHOTO DIODE ARRAY DETECTOR.
It is Used to take Multi wavelength chromatograms.
2.The purity of the peak is good or not will be known by
PDA.
3.For Example your sample has three componets. each
componenet has different wavelength maxima. in that case it
is not possible by UV in singl injection. we can do it by
PDA Detector only.

4.In case of UV, It is dual wavelength detector only.

Answer / arasu

If you dont know the exact lambda maxima of the material u
should go for PDA
Peak purity also we can check if u go PDA

Answer / viswanadham.dama

1. PDA detector gives peak purity and single point
threshold limit.
2.Fast analyis i.e., PDA detector derive multi chromtograph
from single injection where as in UV detector its not
possible.

Answer / 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
