An inexpensive photoreactor using LED light sources and a fibre-optic CCD spectrophotometer as a detector was built by designing a special cell holder for standard 1.000 cm cuvettes. The use of this device was demonstrated by studying the aqueous photochemical reaction of 2,5-dichloro-1,4-benzoquinone. The developed method combines the highly quantitative data collection of CCD spectrophotometers with the possibility of illuminating the sample independently of the detecting light beam, which is a substantial improvement of the method using diode array spectrophotometers as photoreactors.
通过设计用于标准 1.000 cm 比色皿的特殊池架，构建了一个使用 LED 光源和光纤 CCD 分光光度计作为检测器的廉价光反应器。通过研究 2,5-二氯-1,4-苯醌的水溶液光化学反应，展示了该设备的用途。所开发的方法将 CCD 分光光度计的高度定量数据收集与独立于检测光束对样品进行照明的可能性相结合，这是使用二极管阵列分光光度计作为光反应器的方法的重大改进。
