Abstract:
1. A method for determining a concentration of a component of a sample, the method comprising: [1] trapping a volume of the sample in a trapping chamber; [2] passing at least a portion of the trapped volume of sample into a sensing chamber, wherein the sensing chamber includes or is in connection with a sensor; [3] detecting a change in current as a result of interaction of the sample with a sensor; [4] using at least Mathieu's Equation with a value for each of its initial conditions, to determine when a value associated with the detected current is in a stable domain; [5] when the value associated with the detected current is not in a stable domain, varying one or more of the initial conditions of Mathieu's Equation, and repeating the determining until the detected current is in a stable domain; and [6] determining the concentration of the component of the sample using the value associated with the detected current.
