光电微量氧分析仪的改进

Improvement of a Photoelectric Trace Oxygen Analyzer

简要介绍光电微量氧分析仪的改进。通过仪表几个重要特性的试验数据，概述黄磷反应室三种结构对氧与黄磷反应的影响，并就其反应机理作了理论分析。通过试验数据论证了设计改进的Ｌ—３型反应室结构克服了原黄磷反应室的不足，具有最佳的测氧精度与线性度，从而使黄磷发光法的技术特性大为提高。

Improvements of a photoelectric trace analyzer are briefly in troduced. On the basis of test data representing important charateristics measured by relative instru- ments influences of three structures of a yellow phosphorus reaction chamber on reaction of oxygen and yellow phosphorus are described. The reaction mechanism is theoretically ana- lyzed. According to the test data L-3 reaction chamber structure improved is demonstrated and disadvantages of former yellow phosphorus reaction chambers are overcomed. The reac- tion chamber can provide optimum oxygen measurement accuracy and linearity, resulting in significant increase of technical characteristics of yellow phosphorus luminous method.
