Paper Abstract

Opto-chemical sensors are sensors of quantities (pH level, heavy metal ions concentration), detection of which can be performed optically. These sensors utilize various optical phenomena such as changes of fluorescence in the presence of a certain agent. Many substances available and interesting from the sensor point of view exhibit different properties in solution and after physical and/or chemical mounting on glass slide or optical fiber. Because of this it is necessary to investigate application possibilities of a certain substance in well defined metrological environment. In this paper we described system for measuring fluorescence of sensing materials. We proposed system utilizing emission and absorption spectra separation and phase-sensitive detection. As an example of such system a fluorescence sensor of cobalt was of our interest. We described sample preparation process and measured some properties of chosen chemical substances. Achieved results are the basis for further research.
