    摘要： A sorbent media protective device includes an enclosure having a gas inlet, gas outlet and a thin-film multilayer indicator. The thin-film multilayer indicator is proximate sorbent media that can sorb a vapor of interest flowing from the gas inlet towards the gas outlet. The indicator includes a porous detection layer whose optical thickness changes in the presence of the vapor, located between a semireflective layer and a reflective layer permeable to the vapor. With equilibration at the applied vapor concentration between at least a portion of the media and the vapor, the vapor can pass through the reflective layer into the detection layer and change the detection layer optical thickness sufficiently to cause a visibly discernible change in the indicator appearance if viewed through the semireflective layer.
