Abstract
Devices and techniques for estimating the concentration of one or more agents in a fluid environment employ a plurality of measurements of a sensor attribute that changes in response to an agent. Measurements taken before the agent/reagent combination reaches a steady-state may be used. The plurality of measurements are processed using a nonlinear, parametric model of the interaction between the sensor and the agent to determine the concentration of the agent. The model takes into account the finite capacity of a sensor reagent. The model characterizes the interaction of individual agent/reagent combinations with a set of parameters. These parameters require minimal testing to calculate. The invention enables the response of a sensor to an agent over the entire range of agent concentration levels to be efficiently and accurately characterized. The invention also enables the prediction of collective responses given parameters characterizing a plurality of agent/reagent combinations.
