Abstract
Systems and methods which use an optical sensor and an electromagnetic sensor in cooperation for detecting concentrations of one or more materials in solutions are described. In operation according to embodiments of a cooperative optical and electromagnetic sensor material concentration detector, both an optical sensor and electromagnetic sensor are used in cooperation to detect a concentration of a material having a physical feature that is otherwise incompatible with one or the other sensors and/or a material for which measurement is affected by another material present in the sample. Embodiments are, for example, configured to provide a cooperative implementation of optical and electromagnetic sensors operable to detect concentrations of metal ions and acid in a solution, such as for use in real-time material concentration detection.
