新型偏振荧光化学分析传感器

A New Polarization Fluorescence Chemical Analysis Sensor

本文描述了一种基于简单光源、双光电池和惠斯通电桥的新型偏振荧光化学分析传感器。这种传感器可测量荧光物质浓度和pH 值，所用电子仪器简单，可用电池电源，测量精度高，应用范围广，非常实用。

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.
