Bromate in flour applying Inline Dialysis and conductivity as well as UV/VIS detection and PCR

Potassium bromate is used as a flour improver. The determination of the carcinogen bromate in flour requires extraction and additional sample preparation. In this application, Inline Dialysis is used after sonication and centrifugation of the extraction mixture. Bromate is detected by conductivity following suppression and UV/VIS detection and post-column reaction.
