SHEAR HORIZONTAL-SURFACE ACOUSTIC WAVE SYSTEM AND METHOD FOR MEASUREMENT AND SPECIAION OF HYDROCARBONS IN GROUNDWATER

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. 种检测用于感测水溶液中的分析物的系统和方法中的碳氢化合物的方法的示例实施例，包括预处理水样品以提供测试样品。流动池包括具有聚合物涂层的至少个传感器，聚合物涂层对至少种分析物具有至少部分选择性。流动池接收测试样品和参考样品。使用传感器响应的模型和组卡尔曼滤波器利用微控制器处理来自至少个传感器的至少个输出信号，以估计水溶液中的至少种分析物的浓度。
