The KRC Photochemical Post-Column Reactor is used for the photo-derivatization of aflatoxins with HPLC-FLD. This method does not require any chemical reagents, can effectively enhance the fluorescence intensity of aflatoxins B1 and G1, and their sensitivity can reach 0.1 ng/mL (depending on the detector sensitivity). In addition, it is also suitable for derivation of barbiturates, amino acids, peptides, vitamins and sulfa drugs, etc. The whole machine adopts black coating and pure stainless steel body frame, and the shape design is simple and elegant. KRC can be used directly with LC of Agilent, Shimadzu, Waters, Hitachi, Dionex and other brands.
