Claim 8:
9. An infrared (IR) sensor for detection of an analyte in a fluid, the IR sensor comprising:
a housing;
a reservoir disposed in the housing and configured to contain the fluid;
a fluid channel in communication with the reservoir;
a preconcentration material associated with the fluid channel, wherein the preconcentration material enhances IR bands in an IR spectra;
an IR source configured to transmit IR light towards the fluid channel and the preconcentration material, wherein a spectral characteristic of the IR light is changed by the analyte in the fluid in the fluid channel that is trapped in the preconcentration material; and
an IR detector configured to receive IR light transmitted through or reflected off the preconcentration material and detect the spectral characteristic.
