Patent ID: 6962675

Claim:
A system for identifying an analyte in a fluid, comprising: a fluid flow chamber having a first end and a second end; a sensor array including at least a first sensor and a second sensor in an arrangement in the fluid flow chamber such that at least the first sensor is proximal to the first end of the flow chamber and at least the second sensor is proximal to the second end of the flow chamber thereby having a defined fluid flow path, wherein a fluid moving in the fluid flow chamber contacts the at least two sensors at different times; a measuring apparatus coupled to the sensor array, the measuring apparatus being configured to detect a response from the first sensor and the second sensor upon exposure of the sensor array to the fluid; and a computer configured to generate data indicating the analyte in the fluid based on a spatio-temporal difference between the responses for the first and second sensors and identifying the analyte based upon the spatio-temporal difference.
