Sorption-based sensing system

Abstract

The present invention relates to a sorption-based sensing system for sensing multiple selected species in a fluid. In one aspect, the sensing system comprises an optical conduit for guiding light from an input end to an output end, a detector for detecting at least one feature of the light at the output end associated with the optical characteristic, and an analyzer for determining at least one attribute of at least one of the multiple selected species in the fluid based on the detected feature. The optical conduit includes a sorptive portion having a set of different sorption properties associated with the multiple selected species. The sorptive portion is adapted to be positioned in the fluid to reversibly sorb at least one of the multiple selected species to vary an optical characteristic of the sorptive portion. In another aspect, there is provided a corresponding method for operating the sensing system.
