Enzymatic detection device for detecting a gaseous or aerosol substance

摘要

The invention is directed to a detecting device for detecting gaseous substances and aerosols with the aid of an enzymatic reaction. This reaction takes place between a reactant and an enzyme which, on the one hand, is exposed to the substance to be detected and, on the other hand, is held by a carrier which in the form of a porous holder is in contact with a solution activating and maintaining the enzymatic reaction. The properties of the solution are changed by the enzymatic reaction and are evaluated. The detection device is so improved that a capability for evaluation is made possible which is quantitative and which is specific for a particular substance to be detected. The substance to be detected as a reactant can be stoichiometrically transferrable into a reaction product for quantitatively determining the substance to be detected by means of an enzymatic reaction.
