Abstract

Methods and apparatus are provided for accurately determining the concentration of a selected compound or compounds in a multiple component fluid, by reducing or eliminating the interference of non-selected compounds in the fluid. In the method of the invention, the concentration of one or more compounds in a test sample fluid which contains at least two compounds is determined using at least two amperometric or potentiometric membrane sensors which have different specificities and which have been calibrated to determine the individual response-to-concentration ratio of each sensor to the selected compound and non-selected or interfering compound. The concentration of the selected compound is determined by simultaneously measuring the response of each membrane sensor to the test sample and computing the concentration of the selected compound using the simultaneously measured responses to the test sample fluid and the calibrated responses of the sensors.
