Claim Text:
1. A detection system for detecting analytes of interest present in a gas sample, comprising: a layer of porous material, positioned at the surface of a substrate so as to extend longitudinally along a fluidic flow path of the gas sample, said porous material containing a plurality of probe molecules, each probe molecule being able to react with the analyte of interest by causing a change in the spectral properties of said probe molecule; a pump for generating a flow of the gas sample along the fluidic path so that the gas sample comes into contact with said layer of porous material; and at least one optical detection device capable of successively detecting, at distinct detection areas of said porous material layer distributed along said fluidic path, a change in the spectral properties of at least one of said probe molecules, wherein the optical detection device comprises
