Abstract
An exemplary embodiment of a method of detecting hydrocarbons in Systems and methods for sensing analytes in an aqueous solution, include pretreating a water sample to provide a test sample. A flow cell includes at least one sensor with a polymer coating having at least partial selectivity for at least one analyte. The flow cell receives a test sample and a reference sample. At least one output signal from the at least one sensor is processed with a microcontroller using a model of the sensor response and a bank of Kalman filters to estimate a concentration of at least one analyte in the aqueous solution.
