Abstract

A process for enriching substance emissions released from an object in the form of gases, vapors or aerosols, wherein the substance emissions are fed to an adsorption layer by diffusion or penetration and are enriched in the adsorption layer. The substance emission of an object is selectively detected according to the present invention by the adsorption layer being fixed on the surface of the object emitting pollutant, which surface is to be analyzed, by means of an adhesive tape projecting over the adsorption layer on all sides to offer adhesive surfaces for application to the object and to hermetically seal the adsorption layer against the ambient air. A nondestructive adsorption system is also provided, with direct or immediately following analysis for the rapid qualitative and/or quantitative determination of pollutants (e.g., gases, vapors, dusts) by means of a chemical or biological reaction, in which, e.g., specific biomolecules for selectively converting or selectively binding the collected or enriched pollutants and a system for displaying or identifying this conversion and/or binding are used.
