UVE™ Photochemical Reactor

UVE™ Photochemical Reactor provides enhanced detection in trace HPLC analysis of aflatoxins in foods, phenyl urea herbicides in water, barbiturates in blood samples and other compounds. The technique is user-friendly and yields comparable results to electrochemical detection with Kobra cell for aflatoxin analysis. The low inherent fluorescence of aflatoxins B1 and G1 makes derivatization necessary for fluorescence analysis to comply with analytical limit values. This can be carried out easily, conveniently and inexpensively with the UVE using photochemical radiation with UV light at 254 nm, which leads to stable, measurable fluorescence. No additional reagents need to be added. The UVE is simply placed between the HPLC and detector. Aflatoxins B1 and G1 are transformed into stable fluorescent derivatives resulting in clear peaks with enhanced sensitivities when they pass through a special knitted reactor coil with a standard volume of 1.0 mL that is exposed to UV light from a 254-nm low pressure lamp with cooled reflector tube.
