Abstract
Painstaking spectrophotometric investigation was carried out on organo-metallic compounds to identify the most suitable compound for the detection of oxygen. A bis (histidinato) cobalt(II) solution was chosen, characterized by an absorption change at ? = 408 nm as a function of the molecular oxygen concentration in the surrounding environment. An optical fiber system was developed that makes use of a halogen lamp as the source and an appropriate electronic circuit as a detection system. The optrode is very small hollow fiber membrane filled with the solution and coupled with optical fibersFile in questo prodotto:
