WebChlorate and perchlorate have traditionally been analyzed by ion chromatography, which requires the use of specialized equipment. This application note evaluates the performance of the ACQUITY UPLC I-Class System, coupled with the Xevo TQ-XS Mass Spectrometer, for the determination of chlorate and perchlorate in dairy products. WebTo investigate the effect of dissolved oxygen on perchlorate reduction, anaerobically grown cultures Dechlorosoma sp. KJ, were exposed to dissolved oxygen for various periods ranging from 1 to 32 h. Perchlorate reduction and redox potential were then measured for cells returned to an anaerobic environment containing an oxygen scavenger. It was ...
