Abstract
The combination of a solid state peroxyoxalate chemiluminescence detection system with a post-column photochemical reactor is described for the detection of compounds exhibiting low UV absorbance. The photochemical reactor drives a sensitized photooxygenation reaction catalyzed by anthraquinones, whereby hydrogen is abstracted from analytes having weak CH bonds to form H 2O 2. The H 2O 2 is detected by chemiluminescence in a detection system consisting of a short reaction column packed with bis-2,4,6-trichlorophenyloxalate and a quartz flow cell containing aminofluoranthene immobilized on glass beads. The applicability of this photochemical—chemiluminescence detection system is demonstrated for a variety of compounds of pharmaceutical interest.
