Difference between UV and PDA Detector in HPLC
HPLC PDA Photodiode array detector. The UV, VIS and hplc PDA are classified as absorbance detectors; they have a better sensitivity to the picogram (~ PG) levels and use them to detect compounds that have chromophore (light-absorbing compounds). UV is a widely used detector for ultraviolet spectroscopy as well as high-performance liquid ...
