Normal means UV. U can analysis max 2 wavelengths. But in PDA u can analysis range 190 to 800 nm. Also u can check peak purity by using this PDA.

UVdetector: detect fixed nms( 254nm)
PDA detector: multi nms can detect (190-780 nms) and used stress study for Peak purity scan 3D images and method validation purpose

My question about gas chromatography sulfur chemiluminsecence detector. I test unknown sample gas by GC-SCD (calibrated ) and the result of *H2S is 279 PPM , *but when I test the same sample with the GC-TCD (calibrated ) the value of *H2S is 2500 PPM . I'd like to inform you that both GCs are calibrated and have very good operation conditions with stable parameters . the question is if the sample gas with higher H2S over detection limits of SCD detector (1000 ppm). why the result it 279 ppm Best regards
why we are analyzing purity on HPLC why not in gc
