Chemical sensors
A Los Alamos chemical sensors program has been developed to provide sensors for in situ, real-time monitoring of chemical processes. Research on new sensors is focused on developing new polymer chemistries that are rugged and selective for specific analytes. These chemistries are applied to fiber optics for spectroscopy, microelectrodes for electrochemistry, or quartz crystal microbalances for mass measurements. Much of our effort thus far has been on the development of sensors to measure highly acidic solutions using the absorption of indicators encapsulated in acid resistant polymer blends. This sensor is based on internal reflection spectroscopy using fiber optics. Other current research includes the development of an anion sensor for fluoride using an electrochemical technique. The chemistry involves the change in electrochemical behavior of metal-porphyrin complexes with the addition of fluoride ions to a vacant coordination site of the centralized metal ion. This report reviews our philosophy for chemical sensors development and research progress through the end of 1988. 12 refs., 11 figs.
