【Abstract】 This paper describes a new polarization fluorescence chemical analysis sensor based on an un-expansive light, a dual photocell and a Watson bridge. The sensor can measure fluorescence concentration to an accuracy near 2% at 1mm fluorescent, and pH values accurate to 0.02pH units. The sensor requires only simple electronics, which can be battery powered. The sensor can be applied with any fluorescent sample that displays a change in intensity. One can imagine this sensor being used to develop portable point of care clinical devices.更多还原
