Pre-column (hnu-HPLC) photochemical reaction for the on-line characterization of photoproducts using p-aminobenzoic acid as a model substance.
A special photochemical reactor on the basis of high-pressure resistant reaction coils has been constructed, which can be coupled to an HPLC-system before the separation column. By means of the so-called "on-line pre-column (hv-HPLC)"-method, the starting compounds can be irradiated on-line, the conversion products formed can be separated and detected subsequently. The efficiency of the proposed method was proved by using p-aminobenzoic acid (PABA) as a model substance.
