Abstract
The invention provides an analytical device, and method of using same, for detecting a gaseous or volatile analyte and adaptable to be applied directly to the surface of a solid material from which said analyte is emitted. The device comprises a substrate for disposition adjacent a surface of the solid material, and applied to the substrate are (a) an analyte-reactive component which reacts with said analyte, and (b) an indicator in sufficient quantity to produce a detectable signal selective to the reaction thereby detecting said analyte. The analytical device has no exogenous reagent.
