Abstract
A detector, which is source specific, for detecting a fugitive emission from a component containing a gaseous or volatile analyte, and is adaptable for adjacent disposition to the component. The device includes (a) a substrate for disposition adjacent the component from or through which the analyte is emitted, said substrate being substantially inert to the analyte, (b) an analyte-reactive reagent, and optionally (c) an indicator. The substrate is isolated from the ambient air or atmosphere, and no exogenous reagent is utilized by the detector or in the process of detection. When the detector is applied adjacent the component, a detectable reaction occurs (e.g., color-forming reaction or signal) with the analyte emitted.
