PHOTO DIODE ARRAY DETECTOR WORKS JUST AS SIMPLE UV
DETECTOR,BUT ONL Y THE BASIC DIFFERENCE IS THAT PDA IS USED
TO OBTAIN THE SPECTRUM ,MEANS IT IS USED TO SCAN THE SAMPLE
THROUGH OUT THE SELECTED WAVELENGTH RANGE WHILE IN UV
DETECTER WE CAH TAKE THE ABSORBANCE OF SAMPLE AT FIXED
WAVELENGTH.
IN CASE OF PDA FUNCTION, FILTER OF SPECTROSCOPE ALLOWS TO
PASS ALL THE SELECTED WAVELENGTH'S RAY OF LIGHT REFLECTED
FROM GRATING AND THUS WE GET SPECTRA.
SO , PDA CAN BE USED FOR SPECIFICITY STUDY.
