    摘要: A system and method of alternately purging an in-situ sensor with clean fluid and sampling a fluid volume of interest, in order to eliminate drifts and errors associated with the absorption of chemicals to the sensing elements of in-situ sensors. The system and method effectively processes the output of the in-situ sensor using this alternating sample and purge cycle to detect and identify chemicals accurately and reliably. The system and method also effectively reduce errors induced by temperature and humidity drifts in the ambient, and the sampled, fluid.

    摘要: Disclosed herein are methods of analysis for unmixing non-linear, cross-reactive sensors and related system. Use of the disclosed methods, related systems and computer program product permits better analysis of the magnitudes of various stimulants including but not limited to chemical concentrations. One method may add one or more additional signal vectors to the sensor response before linearizing each channel. A second method may add one or more exponential terms to the response curve when using curve parameterization to unmix the sensor response. A third method may use non-linear iterative solutions that estimates an optical depth, linearizes the optical depth, solves for a correction to the estimated optical depth, and updates the optical depth. Also, the disclosed methods and related systems include combinations of the methods described herein.
