Direct Characterization of Proteins and Peptides in HPLC by Photodiode Array UV-VIS Detection: A New Approach in the Detection and Characterization of PolypeptidesPhotodiode-array ultraviolet visible (PDA.UV/VIS) detectors are becoming increasingly useful, since they can continuosly monitor all ...
Method for extraction and determination of amoxicillin, caffeine, ciprofloxacin, norfloxacin, tetracycline, diclofenac, ibuprofen, nimesulide, levonorgestrel, and 17α-ethynylestradiol exploiting micellar liquid chromatography with PDA detector and solid-phase extraction was proposed. The usage of toxic solvents...
laboratories. 1940’s – Cary and Beckman First usable measuring instrument Late 1980’s – PDA detection Simultaneous full-spectrum data acquisition (in seconds) 1990’s – Fiber optic and CCD Charged-Couple Array Detectors Typically, S/N is much lower than PDA... ...
Hence, in this study, we present a validated, sensitive, reliable, and cheap narrow-bore LC-UV-ESI-MS/MS coupled to PDA (photodiode array detectors) method for the simultaneous isolation and identification of flavonoids and their glycosidic derivatives in this flower drug. In addition, the ...
