Claim:
1. An analyte sensing system for determining a concentration of least one analyte present in an object (“analyte concentration”) based on rates of diffusion prior to reaching equilibrium (“initial rates of diffusion”), comprising: a diffusion chamber adapted to receive at least a portion of an object containing at least one analyte to be measured; a measurement chamber pneumatically coupled to the diffusion chamber thereby adapted to receive at least a portion of one or more analytes from the diffusion chamber when the one or more analytes are present in the diffusion chamber; at least one sensor positioned in the measurement chamber that is adapted to chemically interact and/or to physically react with a respective analyte; at least one optoelectronic component positioned outside the measurement chamber for remotely detecting the chemical interaction and/or the physical reaction of the at least one sensor; and a controller for determining initial rates of diffusion of the at least one analyte being measured into the diffusion chamber based on signals received from the at least one optoelectronic component, wherein the controller determines the analyte concentration based on the determined initial rates of diffusion.
