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.

Abstract: A process for a pre-concentration unit including: a sorbent material coated passage-way having an entrance for receiving a hydrocarbon-containing groundwater sample and for pre-concentrating the hydrocarbons in a hydrocarbon-containing groundwater sample by successive sorption/desorption cycles, and having an exit for discharging the pre-concentrated hydrocarbons; a heating unit for heating the sorbent material coated passage-way; and; an array of shear horizontal-surface acoustic wave sensors with coatings adapted for detecting and quantifying the pre-concentrated hydrocarbons, disposed at the exit of the sorbent material coated passage-way; and a housing for enclosing the pre-concentration unit and the array of shear horizontal-surface acoustic wave sensors, adapted for continuous use at a body of hydrocarbon-containing groundwater, and coupled to mathematical methods for generating concentrations of specific analytes from both transient and steady-state signals.
